The invention relates to a yarn feed apparatus for a workstation of a cabling machine for feeding a creel yarn from a feed package arranged on a bobbin creel or from a transport conveyor arranged above the cabling machine to a cabling apparatus equipped with a cabling spindle and/or for feeding a starter yarn from the cabling spindle to the creel yarn, a workstation of a cabling machine for producing a cabling twist and a method for feeding a creel yarn using a yarn feed apparatus of this type.

Yarn feed apparatus, workstation of a cabling machine and method for feeding

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.

Control unit for the pneumatic actuation of an active creel

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.
