Definitions

  • a tube splicer is a machine for joining the exposed ends of a flat, sleevelike, unvulcanized rubber inner tube, which has been cut into predetermined lengths according to the size of the tube desired. The opposing ends of the inner tube are clamped in position on the machine and freshly cut. As soon as the cut is completed, the tube ends are brought together and held in compressive engagement for a predetermined period of time to complete the splice. The tube is then unclar'nped and removed from the machine.
  • Some machines employ clamps which are designed to hold only one particular size tube. This means that a large number of clamps must be kept on hand since many different size tubes are manufactured. Moreover, such clamps generally have side sections which are integral with the bottom section making them cumbersome to store and use.
  • the invention is directed to providing and adjustable clamp which is readily adapted for use with a number of different size tubes, and whose component parts are easily stored.
  • the invention is an adjustable clamp comprising a pair of end sections having configured recesses for receiving adjacent sides or edges of an inner tube, and a pair of intermediate sections, which are removably positioned in abutting relation between the end sections.
