Abstract
The invention relates to a yarn guidance rod and to a device for the laying of a yarn on a cross-wound bobbin in a textile machine. A plurality of winding stations installed next to each other is serviced by a yarn guidance rod made of a carbon fiber reinforced plastic which can be moved back and forth. The yarn guidance rod is provided with a sheathing. The yarn guidance rod has segments made of a highly heat-expandable material in order to achieve heat compensation as compared with the textile machine.
Claims8
A yarn guidance rod system for use in laying yarn on a bobbin on a textile machine, said system comprising a rod formed from a plurality of adjacently disposed longitudinal segments, at least two of said segments being carbon fiber reinforced material having a lower heat expansion property than that of a machine frame of the textile machine, at least one of said segments being a high heat expansion segment interposed between said two carbon fiber reinforced material segments, said high heat expansion segment being formed of a material having a higher heat expansion property than said carbon fiber reinforced material segments and the textile machine frame such that said rod comprises an overall heat expansion property essentially equal to that of the textile machine.
