A control unit for pneumatic actuation of a cylinder, in particular an active creel of a textile-processing machine or a cabling machine, having a compressed air inlet for connecting a compressed air supply, a working air outlet for operating the cylinder, which acts at least on one side, a valve unit arranged between the compressed air inlet and the working air outlet, and an operating element for opening the valve unit to trigger a lifting movement of the cylinder. In order to provide a control unit for pneumatic actuation of an active creel, the actuation of the creel being particularly simple by the control unit, so that an operator can use the creel more easily, quickly and safely, and in addition the creel is protected from damage by incorrect operation, the control unit for achieving a self-retaining valve function, in which the lifting movement of the cylinder is fully executed with a single and/or brief actuation of the operating element, and for the control unit is connected to an end position sensor of the cylinder such that, when the end position sensor is activated, the valve unit is closed and/or the cylinder connected to the working air outlet is automatically depressurized when or after an end position is reached.

An automatic yarn feeding system is provided. The system comprises a yarn feeding track which is arranged on the twisting machine in a length direction of the twisting machine and provided with a yarn feeding manipulator walking along the yarn feeding track; and a supply zone which is arranged on one side of the yarn feeding track and used to buffer base yarns. The yarn feeding manipulator is used to convey the base yarns from the supply zone to a yarn feeding creel of each spindle position. The yarn feeding track is located in the middle of the top of the twisting machine. The supply zone is provided with a structure for buffering a plurality of base yarns, and is located on one side of an end of the yarn feeding track on the top of a control cabinet.

The present invention generally relates to manufacturing of a composite armature, more particularly, to apparatuses for helically winding of a winding roving about a rod when manufacturing a composite armature. There is provided is a helically winding apparatus allowing use of internally unwound roving bobbins instead of sheaves. The helically winding apparatus for a composite armature production line, the apparatus comprising: a disk-shaped creel (1) rotatable about its axis, wherein at least two drums (2) designed to have internally unwound direct roving bobbins mounted therein are mounted on a base of the disk-shaped creel, and each drum is configured to rotate about its axis and to unwind direct roving threads from a bobbin inner side, wherein each drum for placing bobbins of the direct roving is provided with a thread tensioner (3) placed thereon to provide twisting of the direct roving thread relative to its axis when the drum is rotated about its axis to form a twisted roving, wherein the helically winding apparatus further comprises: a cylindrical sleeve (4) positioned in a center of the disk-shaped creel and configured to pass a reinforcement rod through a center of the cylindrical sleeve, wherein the cylindrical sleeve has holes (5) for passing the twisted roving therethrough and helically winding of the twisted roving about the reinforcement rod when the disk-shaped creel is rotated about its axis. A technical effect provided by the claimed invention is an increased produceability of the helically winding apparatus, increased productivity, and a reduced rejection rate.
