A textile machine with multiple workstations equipped with a yarn processing device, and a drive shaft extending along multiple workstations, each yarn processing device connected to the drive shaft by a continuous traction means, and the drive shaft including multiple drive devices each guiding a continuous traction means. Each drive device has two grooves coaxially to the drive shaft, one of the grooves being part of a free wheel about the drive shaft. An output means is connected to each yarn processing device, each output means having front and rear guide grooves, the front groove at a free end of the output means and the rear groove adjacent the associated yarn processing device. Each traction means has one loop engaged in the rear groove of the associated output means and another loop engaged in the front groove through 180 degrees.

Textile machine with a plurality of workstations

A two-for-one twisting or cabling spindle apparatus () with a supply bobbin () mounted on a pot base () of a stationary protective pot () and a spindle () arranged below the protective pot () to guide a yarn () to be processed during a twisting or cabling process. The spindle () is rotatably mounted by a lower bearing device () in a bearing housing () fixed on a spindle rail () and an upper bearing device () mounted to the stationary protective pot (). The largest diameter (d) of the rotatably mounted spindle () is at least 10% less than the diameter (D) of a touching line () of the pot base () of the stationary protective pot () with the yarn ().

Two-for-one twisting or cabling spindle

Wind-on device for workstations of two-for-one twisters and ply twisters with a take-up bobbin, a drive shaft extending in the longitudinal direction of the machine, a friction roller which is driven by the drive shaft and causes the take-up bobbin to make a rotational movement, and a driven advance roller positioned upstream of the friction roller in the yarn run. According to the invention, in addition to the friction roller (), the advance roller () is also driven by the drive shaft () and in that the advance roller () is mounted on a support element () and can be pivoted together with the support element () about a pivot axle selectively into an operating position or into a higher situated service position.

An actuating valve has two relay valves connected to a compressed air source and a pneumatic cylinder with two pressure chambers. When one relay valve is actuated, one pressure chamber is pressure-loaded and the other is relieved. Two 3/2 port directional control valves are arranged upstream of the pneumatic cylinder. Two check valves are positioned in branch lines connecting the relay valves and the directional control valves. A control line connects the branch line to the other directional control valve, respectively. The directional control valves are moveable between a first position allowing compressed air to pass and a pressure relief position. When the relay valves are inactive, the directional control valves are in the first position and the relay valves are in a venting position for the branch lines. When one relay valve is actuated, it assumes a position allowing passage of air to the branch line connected to it.
