 MACHINE FOR IMPREGNATING TIRE FABRIC. 



'T~'1R1^ fabric is subjected to vacuum and then passes by means 

 •*• of a channel through an impregnating chamber containing 

 rubber solution that forms a seal for the channel. 



A vertical sec- 

 tion of the ap- 

 paratus is here 

 shown, A being 

 the vacuum 

 chamber en- 

 closing the 

 fabric-roll B, 

 and C is the 

 channel com- 

 m u n i c a t - 

 ing with D, the 

 solution tank, 

 E indicates the 

 drying rolls 

 and F the fa- 

 bric wind up 

 roller. 



In operation, 



the free end of the fabric is fastened to a cross-bar attached 

 to a pair of metal ribbons, the ends of which are coiled on roll 

 G, the other ends passing downward through the channel and 

 impregnating tank and are attached to the roll H, which is 

 revolved by hand, threading the fabric through the apparatus. 

 The fabric is then attached to the apron / which carries it be- 

 tween the drying rolls and finally to the wind-up roll.

MACHINE FOR SPLITTING EXTRUDED DOUBLE SOLID TIRES. 



The double tire A shaped by extrusion through a die is fed 

 along a roller track B by profiled rollers C and CX and severed 

 longitudinally by a ro- 

 tating disk E working 

 in a guard F. This is 

 provided with exten- 

 sions adapted to divert 

 the severed sections 

 through a right angle to 

 facilitate their delivery 

 on roller tracks I, J by 

 a roller G and coacting 

 weighted roller H. 

 The rollers C and CX 

 may be replaceable or 

 mounted for lateral 

 adjustment. Water may 

 be supplied to the cutter 

 E to facilitate cutting, 

 and the cutter may be 

 laterally adjustable or replaced by a band knife. (Dunlop Rub- 

 ber Co., C. Macbeth, and 11. Willshaw, 14 Regent street, West- 

 minster, England. British patent No. 130,116.)
