Abstract (en)
[origin: US4630785A] A coiler comprises an expanding core comprising a tubular coiler shaft and an expanding mechanism, which is accommodated in the tubular coiler shaft and operable to extend heatable extensible segments. Heat insulating material and cooling means are provided between the heatable part of the expanding core and the coiler shaft. In order to restrict the dissipation of heat. Pressure applying tubes having axes which are radial with respect to the coiler shaft are provided between the expanding mechanism and the extensible segments. The wall thickness of said pressure applying tubes increases toward the extensible segments. Cooling means are provided between the pressure applying tubes and the expanding mechanism.
