DEVICE FOR MOUNTING THERMALLY SHRINKABLE TUBE

摘要

Apparatus draws a continuous length of shrink tubing from a reel, cuts off a section, and advances it onto the terminated end of a lead carried by an adjacent conveyor. This is accomplished by shear blades integral with jaws which close on the end of the tubing to sever a section and contain it and shape it between the jaws. The jaws move vertically in a plate which is then advanced horizontally toward the lead. A feed clamp which descends with the jaws draws the continuous length forward then releases vertically as the jaws depart and a stationary clamp grips the tubing while the jaws and clamp return over the tubing for the next shearing and advance operation. Above motions are effected by levers and a slide driven by followers riding in cam grooves on discs carried by a single shaft. The end of the lead with tubing section thereon is transported laterally through a hot air duct type heater having slotted walls which permit passage of the lead therethrough.
