Abstract:
A web-handling machine for guiding a continuous web of paper or like material along a predefined path, comprising:(a) a tension member;(b) a drive mechanism for moving said tension member between a working position, in which said tension member is held contiguous to the predefined path of the web for holding the web under tension, and a retracted position, in which said tension member is held away from the predefined path of the web for relieving the web of tension; and(c) a control mechanism connected to said drive mechanism and adapted to operate said drive mechanism so as to automatically move said tension member to the working position in response to an operation signal received by said control mechanism when the web-handling machine is operating, and adapted to operate said drive mechanism so as automatically move said tension member to the retracted position in response to a non-operation signal received by said control mechanism when the web-handling machine is not operating;whereby the web can be prevented from curling due to being held still and under tension against the tension member during the non-operation of the web-handling machine.
