IMPROVED TIRE BUILDING MACHINE. 



TiiK .iiipruvtd tiri-lnnliliiig machine licre shown consists of 

 two parts, a winding and stitching unit and a tension unit, 

 both being doweled and bolted together forming a complete 

 machine. It is used for the manufacture of fabric tires and lor 

 smaller sizes of cord tires. The capacit>' of the machine is 

 50 to 120 carcasses in a 10-hoiir day with one operator. 



In operation, the roll of frictioned fabric is placed in the ma- 

 chine and the loose end threaded over the tension rollers and ap- 

 plied to the core. When this revolves it pulls the fabric over 

 the tension rollers and lays it on the core. The speed of the 

 core is controlled by gearing on the tension rollers so that the 

 fabric cannot be applied to the core faster than the predetermined 

 stretch in proportion to the gears and the tension rollers. Thus, 

 the fabric will be stretched uniformly on all cores, regardles-. 

 of width or variation of any kind, and can be measured tn 

 exact length and uniformly stretched, bringing the ends t.* 

 gcthcr. 



When the machine has completed one revolution the fabrir 

 is cut off. the splice made, and the ply stitched down on the 

 core. The next ply is put on in the same manner and when 

 the proper number have been applied to the core, the bead is 



and the bottom of the fabric is cleaned in passing over the top 

 tube. The tubes arc of brass and properly slotted, with adjust- 

 able cover to tit any size of fabric, up to and including 92 inches. 



are added and stitched dov 

 trimmed and the carcass 



placed, anil the remaining plies 

 separately. The tire is then 

 finished. 



This machine is unique in that as soon as the fabric is cut 

 off, all sides of the core arc available for inspection or removal, 

 and no part of the machine overhangs it, or interferes at the 



sides with the handling or manipulation

TIRE FABRIC CLEANING MACHINE. 



Vacuum cleaning 'has been used for some time in removing 

 from factories dust and dirt of every character, but the direct 

 application <i{ air cleaning in rubber mills is comparatively recent. 

 That the Tuec air-cleaning system is being successfully used in 

 cleaning and renovating tire fabrics may be seen in the illustra- 

 tion. 



This apparatus is used in connection with a stationary cleaner. 

 The top of the fabric is cleaned in passing over the bottom tube. 



Renovating Liners. 



These tubes pass from 160 to 320 cubic feet of air per minute, 

 thus the fabric is given an air bath, removing soapstone, lamp- 

 black and other substances adhering to the fabric. (The United 

 Electric Co., Canton, Ohio.) 



VULCANIZER FOR FACTORY DAMAGED RUBBER GOODS. 



Tire manufacturers can make firsts out of factory damaged 

 casings by using the spot vulcanizer here shown. The clamp 

 carries a steam plate IH by 3 inches and is provided with a 

 rocking table inside the casing making it self-adjusting to any 

 uneven thickness. It is used in footwear and druggist sundries 

 factories and also for repairing inner tubes. 



To set up the vulcanizer, run two headers along the wall, 

 one for steam, the other for condensation. One set of headers 



The Si- 



can be used for several units placed about two feet apart. A 

 short length of chain with a hook on the end, attached to a 

 piece of rope from the ceiling should be provided to hold the cas- 

 ing in the desired position. (G. S. Andrus, Akron, Ohio.)
