Shoe Machine: Making Better Welcoming Shoes

< p > in every field of < a href= "//www.sjfzxm.com/news/index_x.asp" > shoes > /a >, the quality and performance vary with the overall degree of care of the material and manufacture.

In Goodyear (Goodyear)'s shoe making process, there are a number of important processes that clearly indicate why we need so much technology and attention to detail to produce the best products.

< /p >

< p > < strong > inner bottom plus border < /strong > < /p >

< p > inner bottom is the basis of < a href= "//www.sjfzxm.com/news/index_x.asp" > shoes > /a > because each step depends on the quality of its preparation.

In particular, the positioning of the inner bottom welt has a direct bearing on the strength and ultimate appearance of the shoes.

Many people believe that the insole welt is simply bonded to the periphery of the bottom edge at a fixed distance from the edge. In fact, this distance needs to be changed at least 5 times.

The welt must also start and end at precise points, which are marked in advance to help accurately stitch the welt.

< /p >

< p > although the setting is different from the thickness of the shoe material and the type of welt, figure 1 shows a good average starting point.

The waist of the shoe is set wider, and the appearance of the shoe is more beautiful (the lighter the shoe, the narrower the waist).

The wider shoe waist setting also prevents the "a href=" //www.sjfzxm.com/news/index_x.asp "> sole" /a "suture and swings to the outer edge of the heel abdominal wall.

The setting of the stitch is narrower, making the base line farther away from the vamp and becoming more prominent.

Taking into account the need to increase the thickness of toes, set the median toe.

< /p >

< p > the recognized machine for implementing this operation is produced by the Prime manufacturing company of the United States.

In recent years, several different versions have been produced due to the mechanization of the sewing process.

But in many cases, the machines used nowadays are older than the operators.

This is the case for many professional machines that produce opportunities for footwear. In such a market, there is no need to adopt entirely new machines, and the quality of ready made equipment is high and sustainable.

However, Bima recently introduced a new interior lining machine, featuring ergonomic design and improved installation.

< /p >

The "P" standard Goodyear inside is vertical, so it is necessary to install the middle plate fitted with the inner bar on the traditional front side.

The scraper is used to compress the vamp so that it is close to the supporting inner lining instead of leveling it.

Without it, stitching will be more difficult and less accurate, and additional pressure must be applied to the inner side of the welt to bond with the inner sole.

Some companies supply assembled die blocks to work on the welds, but traditional molds are usually able to add the raised midsole and change the settings of the toe belt and the blade.

As shown in Figure 3.

The modern P sewing machine is very complex and still depends on a lot of operator skills.

< a href= "//www.sjfzxm.com/news/index_x.asp" > shoes > /a > must be fixed so as to stitch the first and the end of the road at a relatively high position.

Suture ends at the heel of the heel or in order to prevent the fishtail phenomenon mentioned above.

It is also important to smoothly slide along the toe of the shoe and ensure that the awl penetrates the upper and inner welt.

If you fail to do this, it will lead to the bottom. You can see that there are sutures on the edge of the leather, which indicates that the manufacturing is poor.

But if there is no good extension, even the best extension sewing machine can not produce very good results.

The magazine World Footwear has analyzed the problems of the Barbour welcoming company from November 2006 to December. This article clearly shows that careful care is needed before producing the high quality shoes.

At present, the progress of stitching bar equipment includes automatic lubrication and low noise and low vibration speed change engines.

< /p >

< p > many experts believe that cutting the outer edge is the highest requirement for all Goodyear processes, because it not only produces the final shape of the sole, but also cuts out the groove and receives the lock stitches connected to the welt.

Accuracy is therefore crucial.

The shape is controlled by two guide bars.

The basic fracture guide bar is along the welds and only used in the waist of the shoe.

Before the stitching, the operator controls the second guide bars controlled by the pedals and releases them on the other side.

The guide bar is directly along the side of the shoe last along the line, so the outboard sewing is not too close to the seam of the welt.

< /p >

< p > apart from heavy shoes, it is a traditional way to sew soles in grooves, because this method sews neat shoes and helps to hide any bad sewing.

This method is almost disappearing due to the cost of opening and closing trenches that require additional operation.

It is also more difficult than accurate cutting grooves.

The key to the two method is to ensure that the grooves are deep enough, so that the bottom of the spindle line is low enough below the sole of the shoe, but not too low to weaken the strength of the suture.

Therefore, in the two case, the setting of cutter is very important.

The correct softening of the sole is also very important, especially for the way to open the groove, because it helps to achieve accuracy and the opening and closing of the groove edge.

< /p >

< p > many old machines are still in use.

They were designed to provide powerful equipment to pierce hard leather "a href=" //www.sjfzxm.com/news/index_x.asp "sole" /a "(the entire thickness is usually about 12mm) while cutting grooves or grooves.

The noise generated by these machines has attracted much attention, especially when used by several machines.

The ESM company in England provides an edge sharpening machine, in which the motor operates only when the shoes are processed.

The machine is placed on the silencer rack with a light beacon, causing the operator to be less affected by noise without affecting the functionality.

The characteristics of this mold are automatic lubrication and variable speed motors for reducing maintenance costs.

< /p >

< p > it is difficult to find a device to make the edges advantageous for sewing and leveling the edges after sewing.

Some companies have built their own devices.

The legend shows the original device, including the copper wheel used to stitch the groove before hammering and consolidating the bond.

< /p >

< p > < strong > sole sewn < /strong > /p >

< p > some may think that this is just the case of retaining the grooves or grooves with the bottom edge machine.

This is not the case.

First, we must set the line tension correctly so that the bottom line (on the sole of the shoe) is locked from the top of the shoe to the top line (on the side of the welt) 1/3.

If it is closer, the surface wear will be too fast.

And if it is located at the joint between the sole and the welt, it will cause the seam to be unstable.

< /p >

< p > the machine also has an adjustable guide bar, which is called the shallow edge attachment, and the edge of the shoe is controlled by it.

Some producers who are not familiar with the process consider this an extra complex factor, but it is absolutely important for the welt shoe, because it determines how far the suture line is on the strip and prevents it from walking too close to the seam of the welt.

If the welt wear is not qualified, this is the most common reason.

< /p >

< p > there are more options for sole sewing.

Recent progress has been made by Falan and Fioretto. It is not necessary for them to use precise cutting of sole and shaving.

The feature of this equipment is to use a cutter in front of the sewing head to cut grooves or gaps in one process and sew it.

< /p >

< p > so what's so special here? There are two ways to nail on the heel.

The most widely used is internal mounting. In this method, nails are removed from the bottom and bottom to the heel after removing the shoe last.

This is a good method without further heavy operation.

However, in the processing of Goodyear's welt, there are all the finishing processes to be executed, including hand holding shoes constantly, and if there are no shoe last in shoes, this will damage the appearance of shoes.

< /p >

< p > external fitting is completed in two steps on the same machine.

In the first step, the base of the heel (with adhesive on both sides, with no heel on the ground) is placed on the sole, and the nails are fastened to the heel of the shoe last.

In the second step, the shoes are turned to the second table, where the ground where the glue is attached is placed in the fixture.

The heel is pressed to the grounding part of the heel, and now the heel is finished, unless it is considered that additional hammer should be applied to the grounding area of the heel.

This system has another advantage, because it does not need to enhance the insole to prevent deformation. This is a very important consideration for the leather insole used in the best addition of welt shoes.

< /p >

< p > Goodyear plus welt is a complex process used to achieve perfection. In order to create a pair of high quality shoes, there are many technical tongs, production and modification processes.

It is not surprising that these products are expensive.

But on the other hand, they are beautiful and durable, and they are worth the money.
