MACHINE FOR IMPREGNATING CORD TIRE FABRICS 



Cc.RD fabrics used in the manufacture of cord tires are impreg- 

 nated with rubber solution before the skim coat is applied by 

 the calender. That constant improvement is being made in 

 the design and construction of impregnators is shown in the 

 accompanying illustration. 



The fabric from the stock roll is fed over a smoothing roller 

 and into the tank, where it becomes saturated with the rubber 

 solution. From the tank the saturated web passes between pres- 

 sure rollers as adjusted, that the solution is forced into the

used as a drilling template or fi.xture. .\ny selection or grouping 

 of nail holes may be made from this template for any size or 

 style of rubber heel, using the back center hole for the men's 

 sizes, and the front center hole, which is ^-inch ahead of the 

 back hole, for women's sizes. 



As the compound used in heels 

 bydififerent rubber manufacturers 

 varies considerably, the shrinkage 

 in the finished heel varies. There- 

 fore, in order to locate the washer 

 pins in the heel molds correctly, 

 a nailing should be selected from 

 the celluloid template, each manu- 

 facturer figuring his individual 

 shrinkage, and the washer pin in 

 the mold located properly to com- 

 pensate for this shrinkage, so that 

 the holes in the finished rubber 

 heel will line up with the holes 

 in the template, as described 

 above. — United Shoe Machinery

interstices of the fabric in an even and thorough manner. The 

 impregnated fabric is then passed in festoons between the steam- 

 heated coils of the dryer, where the solvent is evaporated. 

 While not a part of the equipment, a solvent recovery apparatus 

 can be attached to this machine. 



After drying the impregnated fabric is wound up on a stock 

 shell and is ready for the final skim coat.— The Banner Machine

RUBBER HEEL ATTACHING MACHINES 



Standard machines used for nailing, or for loading and at- 

 taching leather heels to shoes are shown herewith. All three 

 can be equipped for rubber heel at- 

 taching in connection with rubber heels 

 which have been laid out and con- 

 structed for machine attaching. 



The type of machine selected is 

 governed liy the kind of shoe to be 

 manufactured, the amount per day to 

 be made, and the territorial conditions. 

 It requires a complete special nailing 

 outfit, in comparison with that used 

 for leather heel attaching, this outfit 

 being made from a heel of each size 

 and style to be attached. The outfit 

 includes a rubber heel locating ring 

 which supports the heel while the nails 

 are being driven, to prevent expansion 

 of the heel, which would cause the 

 location of nail holes to be changed. 



The celluloid rub1)er heel template 

 shows the proper alinement of the 

 nail holes in rubber heels for machine 

 attaching. This is a reproduction of 

 the die on the heeling machine, and 

 the celluloid template is in no way 



MACHINE FOR CUTTING SAMPLE TIRE SECTIONS 



This device, according to the manufacturer, affords a great 

 saving in labor, time and money over the old makeshift methods 

 of cutting sample sections from tires. It cuts clearly through 

 any tire section, fabric or cord, including the steel bead inserts 

 ordinarily used. Each cut is accurate and true toward the center 

 of the tire, clearly sho'wing up the tire construction. It will han- 

 dle any size tire up to and including an 8-inch cross-section. 

 The maximum width of the sample cut is three inches. An entire 

 tire can be cut up into samples without any w-aste. 



The machine is compactly built on a rigid base casting. The 

 working table in front is adjusted for each size tire. The mandrel 

 for holding the work is located above the end of the table and 

 in line with the main bearing. The circular cutting knife rotates 

 around the forward end of the mandrel. 



The operation of the machine is simple. A mandrel of the 

 correct size is set up and the circular knife is advanced into
