Tension Adjustment In Filamentary Materials
(AREA)
Abstract
A yarn compensating tensioning device, essentially characterized in that it consists of a support fixed to the machine in which the tensioner is to be installed, in which two pairs of opposite, rotating, established plates are located one after the other. so that in each pair one of the two opposite plates is articulated to a fixed part of the support and the opposite plate is to a pivoting and rotating portion of the same support that allows, thanks to the action of a counterweight, to maintain the two plates of the pair applied one on the other leaving however the possibility that they separate when the action of said counterweight is overcome by an excess of traction, fortuitously exerted on the thread that passes through the tensioner, thanks to which the thread itself acts on a lever provocative of the cancellation of the effect of said counterweight.
