Abstract: A belt splicer for butt-welding conveyor belts and methods for its operation. The belt splicer has clamp jaws that close to contact the butt edges of two belt sections against opposite ends of a heating wand and to hold the two melted butt edges together as they weld to each other.

Abstract: The jig of this invention holds a radial array of separate materials together so that they can be glued, welded, or otherwise secured together. The jig is then removed. A plurality of fingers are pivoted to a common support, and elastic means are used to urge the fingers together to tightly grip the radial array of materials to be held. The finger surfaces are angular to correspond to the angle of the materials to be held and for a cross shaped array of materials, the finger surfaces are at 90.degree. to each other. The fingers have shanks that project beyond the hinge or pivot point and these projecting shanks may be used to open up the fingers by manually grasping the projecting shanks and thereby overcoming the elastic means which normally urges the fingers together.

Heat is axially removed from the diaphragm through the mentioned first and second heat sinks during the electron beam welding.

Abstract: An assembly jig including a flexible binder that encircles an assembly of frame members having mitered ends, the binder being attached to a draw bar guided along a guide section of a main support.
