Analyzing The Shoemaking Process Of The Rib Forming

< p > the upper and upper shoe of the main and inner Baotou will be installed on the shoe last with nails that have been trimmed. Through the stretching of the external forces, the upper can be attached to the last body, so that the shaping process is the bandage.

< /p >

< p > (1) < a href= "//www.sjfzxm.com/news/index_c.asp" > bandage < /a > preparations.

< /p >

< p > because of the different assembly methods of the bottom, the way of pulling is different, and the preparatory work is different.

For example, introduce the preparatory work before the stretch, such as shoe upper, a href= "//www.sjfzxm.com/news/index_c.asp" > shoe last "/a", bottom material, accessories and other tie belts (lacing leather shoes). The main and inner parts of Baotou are soft back, and then the pre formed nails are used to repair the inner part of the shoes, and the hoisting side is used for forming.

< /strong > < /p >.

< p > 1. bandaging method: because the operation of the bandage is to press the foot to help the foot by pulling the ribbed nail, it is also called a row of nails, because it has a neat nail on the bottom stubble.

< /p >

< p > 2. before stretching the nail forming method: its technological process is to prepare leather, shoe last, bottom material, accessories and other main fastener, inner Baotou back soft back forming preform nail, inner bottom hanging hoisting front bracket, waist waist nail heel position stereotype.

< /p >

< p > 3. a bandage molding process: the technological process is to prepare the upper, upper, bottom, accessories and other main fastener, the inner and outer sides of Baotou, and then use the brush to dry and activate the last set.

< /p >

< p > 4. drawing method: pull the rope or nylon rope on the side, pull the rope through the rope, and make the material stick to the shoe last.

< /p >

< p > 5. machine stretching method: from the classification of the bandage part, it can be divided into four parts: the front stretch machine, the tension machine, the back stretch machine, the back side machine, the combined boom machine and so on.

< /p >

< p > > a href= "//www.sjfzxm.com/news/index_c.asp" > stretching machine < /a > is to use mechanical pressure tightener and sweep knife auxiliary role to complete the forming of the rib.

The utility model has the advantages of large extension ability, uniform working force, high labor efficiency and low labor intensity.

The main method used in mechanized production.

< /p >

< p > (3) last molding method.

< /p >

< p > the shoe last is pushed into the shoe sleeve through a certain force, from the inner cavity of the shoe, by means of extrusion, punching, and roofing, etc., so that the requirement of reaching the last shape of the shoe is called the last row method, also known as the breaking last method.

< /p >

< p > this method has the advantages of short production cycle and simple operation, but it is easy to appear to be ineffective, the hardness of main heel and inner Baotou is not enough, and the shoe is easy to deform.

So this method is suitable for soft shoes.
