Shoes production line

A footwear[footwear?:Footwear paper pattern cutter] company has mainly four departments in which a progressive route is followed for producing finished shoes[shoes?:shoes paper pattern cutter]. These are- Clicking or Cutting Department, Closing or Machining Department, Lasting & Making Department, Finishing Department and the Shoe Room. The shoes production line can be concluded as follows.


Clicking or Cutting Department
 In this department, the top part of the shoe or the "upper" is made. The clicking operative is given skins of leather, mostly cow leather but not restricted to this type of leather. Using metal strip knives, the worker cuts out pieces of various shapes that will take the form of "uppers". This operation needs a high level of skill as the expensive leather has to be wasted at the minimum level possible. Leather may also have various defects on the surface such as barbed wire scratches which needs to be avoided, so that they are not used for the uppers.

Closing or Machining Department
 Here the component pieces are sewn together by highly skilled machinists so as to produce the completed upper. The work is divided in stages. In early stages, the pieces are sewn together on the flat machine. In the later stages, when the upper is no longer flat and has become three-dimensional, the machine called post machine is used. The sewing surface of the machine is elevated on a post to enable the operative to sew the three dimensional upper. Various edge treatments are also done onto the leather for giving an attractive look to the finished upper. At this stage only, the eyelets are also inserted in order to accommodate the laces in the finished shoes.

Lasting & Making Department
 The completed uppers are molded into a shape of foot with the help of a "Last". Last is a plastic[plastic?:Plastic sample cutting machine] shape that simulates the foot shape. It is later removed from the finished shoe to be used further in making other shoes. Firstly, an insole[insole?:fibreboard insole pattern cutting machine] to the bottom of the last is attached. It is only a temporary attachment. Sometimes, mostly when welted shoes are manufactured, the insole has a rib attached to its under edge. The upper is stretched and molded over the last and attached to the insole rib. After the procedure completes, a "lasted shoe" is obtained. Now, the welt- a strip of leather or plastic- is sewn onto the shoe through the rib. The upper and all the surplus material is trimmed off the seam. The sole is then attached to the welt and both are stitched together. The heel is then attached which completes the "making" of the shoe.

That was the process for heeled shoes. When a flat shoe is in the making, there are considerably fewer operations. The insoles in this case is flat and when the uppers are 'lasted', they are glued down to the surface of the inner side of the insole. The part of the upper, that is glued down, is then roughed with a wire brush to take off the smooth finish of the leather. This is done because rough surface absorbs glue to give a stronger bond. The soles are usually cut, finished and prepared as a separate component so that when they are glued to the lasted upper, the result is a complete and finished shoe. Soles can also be pre-molded as a separate component out of various synthetic materials and again glued to the lasted upper to complete the shoe.

Finishing Department and the Shoe Room
 The finishing of a shoe depends on the material used for making it. If made of leather, the sole edge and heel are trimmed and buffed to give a smooth finish. To give them an attractive finish and to ensure that the edge is waterproof, they are stained, polished and waxed. The bottom of the sole is often lightly buffed, stained and polished and different types of patterns are marked on the surface to give it a craft finished look. A "finished shoe" has now been made.

For shoe room operation, an internal sock is fitted into shoe which can be of any length- full, half or quarter. They usually have the manufacturers details or a brand name wherever applicable. Depending on the materials used for the uppers, they are then cleaned, polished and sprayed. Laces and any tags that might have to be attached to the shoes, such as shoe care instructions, are also attached. The shoes, at last, get packaged in boxes.
