Abstract: 667,110. Tube splicers. WINGFOOT CORPORATION. March 28, 1949. [Nov. 12, 1948] No. 8385/49. Class 70. Tube splicer for butting freshly cut ends of stock comprises guide members 24, 25, whereon the stock ends are positioned, a clamp arm 19, 20 co-operating with each guide member, a carriage 6, 7, for each guide member, a bed 8. Fig. 2 (not shown) for the carriage, a slide member 15, 16 for each clamp arm, the carriages being movable horizontally and the slide members both vertically and horizontally, means for simultaneously moving the carriages and slide members horizontally when the clamp arm and guide members are in clamping position and adjustable stops 74 for defining at least one of the limits of the vertical movement of the slide members. Pressure cylinders 9, 10 move the slide members 15, 16 vertically along machine slides 17, 18. Lateral adjustment of the slide members and slides is effected by screws, Fig. 9 (not shown). The clamp arms. support a plurality of segments 22 which form a flexible unit adjustable by an airbag 23. On inflation the segments are forced down into contact with the upper face of the guide member or the tube thereon. The tube ends are cut by electrically heated knives 53. 54, the guide members co-operating with an anvil 27 moved by a piston-rod 28. Handwheels 34 adjust an abutment block 31 on the guides 24, 25 so that the stock ends may be correctly aligned for butting. When the tube is cut a cushioning effect is obtained through adjustable springs 63 on an element 62 supported between the knives 53, 54 (Fig. 4). A screw on the underside of each carriage limits their movement and also adjusts their lateral position, whereas a linkage system moves them. A solenoid holds the slide members in their upper position and only releases them when both starting buttons 92, 93 are pressed. The adjustment means 74 is set at the beginning of butting and prevents pinching of the stock. A cushion brake 42 halts momentarily the descent of the knives when they first contact the tube, 'and so allows the stock to resume its normal shape, by means of a crosspiece 40 on a knife supporting arm 35 contacting the plunger 43 of the brake 42. Thereafter the cutting is completed, the anvil retracted, the waste ends are blown away and the knife arm 35 raised. The carriages then move towards each other and the stock is butted. A modified form of clamping arm, Fig. 10 (not shown), incorporates a wedge whereby the segments 22 on the outside are at a lower level than those intermediate thus enabling the folded outer ends of the stock to be contracted first. A modified form of guide means is also provided.
