There are disclosed one-piece chuck structures for use in winding machines and particularly, but not exclusively, for use in high speed winding machines for the take-up of synthetic plastics filament. These one-piece chuck structures comprise a first elongated tubular portion adapted to receive one or more bobbin tubes and a second elongated tubular portion integral with the first elongated tubular portion and of reduced external diameter relative thereto. Bearings cooperate with the exterior of the second elongated tubular portion such that the first elongated tubular portion and the second elongated tubular portion are rotatable about a common longitudinal axis. Also disclosed are hollow bobbin tube-engaging elements as well as double-arm tube-positioning members which can be used with such and other chuck structures.

Chuck structure

Method of mounting chuck structures

A chuck for a winding machine has a tube gripping system with rubber or elastomeric springs which generate a bias to press tube gripping elements against the internal surface of a bobbin tube.

Tube gripping system for a winder chuck

An actuating system for a bobbin tube gripper comprises resilient structure held in compression in order to create a force for urging tube gripping elements into engagement with a tube to be gripped. The resilient structure constitutes a body of a porous elastomer.
