Abstract: A device for the thermal treatment of yarns comprising at least one inlet opening and at least one outlet opening for at least one transport means, which transports the yarn through the device, and comprising separating elements at the inlet opening and the outlet opening for thermal shielding, in order to minimise the exchange of media to the environment. The separating elements are configured to have a low bending rigidity and are arranged such that a surface load is applied onto the yarn lying on the transport means, for example a conveyor belt, which is not greater than 0.005 kg*cm?2.

Abstract: 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.

Abstract: 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.
