How to make a shoe?

Shoes have always protected feet from harm and dirt, rough surfaces and bad weather. This product will long remain a clothing accessory, one that must first be attractive before it is worn. Despite mechanisation, the shoe industry is still labour-intensive. 150 operations are necessary to produce a pair of shoes. 3 types of manufacturing technology are discussed:cementing, welted construction (Goodyear), injection moulding.

SHOE: MAKING SECRETS

SHOE: MAKING SECRETS

 


MANUFACTURING PROCESS

Design


DESIGN:
The entire process  starts with the style. Many designs and sketches are made according to fashion. Two collections are prepared each year (summer-winter), taking into account the shapes, colours, materials and chosen accessories.

 

 

 

Modelling

 



MODELLING: The last is made, in a basic size, according to the design of the shoe. The lines of each element of the design are reproduced on the last and stretched (a two dimensional representation) to obtain the standard. These operations are performed very quickly using CAD (Computer Assisted Design).

 


Pattern-cutting






PATTERN-CUTTING:
Whatever the method used, this operation consists in determining the final outlines of the different parts of the sample upper for industrial production.

 

Range (sizes)





RANGE (SIZES):
 The various sizes of the model parts are obtained (scaled up) from the base-size (sample-size) to create a range. Size 41, for example, allows for a range of sizes between 39 and 46.

 

Cutting







CUTTING: 
All the components of the uppers are cut out of selected materials, such as leather, textile, etc., irrespective of the cutting technique used, manual cutting, press-knife cutting, laser or water-jet cutting.

 

Preparation for stitching






PREPARATION FOR STITCHING: 
The various components of the uppers undergo operations such as skiving, folding, perforating, etc.

 

Stitching






STITCHING: To form the upper, the parts are joined together by stitching. Ornamental seams are sewn at this stage.

 

Rough rounding - preparation







ROUGH ROUNDING - PREPARATION:
Bottom parts, such as the insolesole, heel, etc., are assembled using the upper section of the last as a gauge.

 

Assembly area or room





ASSEMBLY AREA OR ROOM:
The last, the upper, the insole and the sole are joined together by pair and size, and the lasts are put together and matched up into sets for the lasting room as required.

 

 

 

 


CEMENTING

Cementing


Technical construction where the sole is bonded by cementing on the tack-lasted upper.

 

Lasting




LASTING:
During lasting, the insole, which is the keystone of the shoe, is positioned on the last. The upper covers the last exactly and the excess material is folded onto the insole to which it is cemented. The operation is performed by machines.

 

Attaching the heel




ATTACHING THE HEEL: In the heel area (back part of the upper), 22 rivets reinforce assembly of the upper to
the insole. This is a mechanical operation and all the rivets are driven in and riveted at the same time.

 

Cementing preparation





CEMENTING - PREPARATION:
To begin, cement is spread on the underside of the upper and on the sole.

 

Attaching







ATTACHING:
The sole is manually positionned on the insole.

 

Cementing






CEMENTING:
The sole is cemented to the shoe through high pressure being applied to the upper part of the shoe.

 

Inspection, cleaning and dressing room







INSPECTION, CLEANING AND DRESSING ROOM:
The shoe is inspected, cleaned, dressed and polished. Heel socks, laces and the brand label are added.

PACKING: The shoe is checked and then packed for sale.

 

 

 

 


INJECTION MOULDING

Various products are positioned in a mould under pressure.

Injection moulding

The upper is inserted into the male mould






The insole is attached to the upper by an overedge seam called a Ströbel,the name of the machine’s inventor. The upper is inserted into the male mould.

 

 

 

The polymeris injected under pressure






The polymer, which becomes liquid when heated, is injected under pressure into the mould of the sole held against the upper.

 




 

 

 


MACHINE WELTED CONSTRUCTION (GOODYEAR)

Machine welted construction (GOODYEAR)


This method was originally performed by hand. It is a shoe construction method in which the welt and upper are sewn onto the insole rib by the welt sewing machine.

 

Le cousu GOODYEAR  : maintenue par pointe




The upper is temporarily fastened onto the last bytacks.

 

 

 

The welt




THE WELT:
The welt gives the construction a particular appearance. It is the means by which the upper, the insole and the sole are fastened to each other.

 

The machine-welted construction GOODYEAR




The seam of the welted construction is invisible
once the shoe is finished. The machine-welted construction is also known by the name of the machine’s inventor, GOODYEAR.

 

Bottom filling




BOTTOM FILLING: 
After the wooden or metal shank has been fastened, the space between the lasting margins of the upper is filled with a mixture of cork and cement or foam.

 

Attaching the sole




ATTACHING THE SOLE: 
The sole is positioned on the bottom of the shoe and cemented. Adhesive is spread on the two parts before they are brought into contact
with each other.

 

 

Lockstitched seam




LOCKSTITCHED SEAM: 
The sole is attached permanently to the welt by a lockstitched seam. This stitching is still visible when the shoe is finished.

 

 

Attaching of the heel






ATTACHING OF THE HEEL: 
The heel is cemented and then nailed to the sole.
