Winding Device with Support Roller and Contact-Force Control Device as well as Yarn Processing Machine

Abstract

The invention relates to a winding device (16) for winding a yarn (20) onto a package tube (22) in order to form a yarn winding package (24). The winding device comprises a spindle (34) for holding and rotationally driving the package tube (22) about its longitudinal axis (30) and a support roller (40) that abuts against the peripheral surface of the yarn winding package (24) during winding of the yarn (20). The spindle (34) with the yarn winding package (24) can be swiveled relative to the support roller (40) by means of at least one pivotably mounted swivel arm (46). The winding device has a contact-force control device (54) with an actuator (56) for the swivel arm (46), with a control device (58) for controlling the actuator (56), and with a bending beam load cell (60) associated with the swivel arm (46). This is used to determine a respective actual value of the contact force FA of the yarn winding package (24) against the support roller (40) with which the contact force FA can be regulated to a predetermined target value by means of the control device (58) through appropriate controlling of the actuator (58). The invention further relates to a yarn processing machine (10) with an aforementioned winding device (16).
