  • Process of making a cloth takeup mandrel
    Patent number: 4754537
    Abstract: A cloth take-up mandrel is fabricated by cutting pipe of a thermoplastic polymeric material (e.g. PVC) to a desired length, heating the ends of the pipe to a temperature at which the polymeric material softens (as by insertion into a bath of glycerine), inserting end caps into the thus softened pipe ends (having a cross-sectional dimension greater than the dimension of the pipe), and cooling the ends with the end caps inserted therein. The invention avoids problems such as splintering associated with conventional wooden mandrels.
