A process and device is provided to handle the yarn after piecing or bobbin replacement where conical bobbins are used. According to the process and with the apparatus, the yarn is transferred to the yarn guide in such a manner that the yarn is first guided in direction of the smaller diameter of the bobbin or former before the winding of the yarn over the entire bobbin width of the bobbin takes place.

Process and device to spool a yarn on a spinning machine/spooling device

In an open-end spinning device a yarn draw-off nozzle suitable to ensure constant spinning conditions even at very high rotational speeds is provided. This is achieved in that the yarn draw-off nozzle is designed so as to be especially capable of heat dissipation and thus being capable of preventing a heat accumulation in the area of the yarn draw-off nozzle thanks to its high capability of heat dissipation.

Open-end spinning device

A yarn draw-off pipe for drawing off a yarn from an open-end spinning device. The draw-off pipe is equipped with first and second pipe sections, which are connected to each other through a connecting piece. The connecting piece contains a chamber and is provided with a deflection surface extending into the chamber. The latter is part of an insert. The connecting piece is provided with an insertion opening for this insert on its side towards the spinning element, when assembled, the insert is secured axially between the front end of the insertion opening and the first pipe section or, alternatively, between the two pipe sections. The insert is made of a ceramic material and, with its end towards the spinning device, projects radially beyond the outside diameter of the first pipe section. The area of the guide left free by the insert is filled with a plastic material.

The housing (1) of a opening device for an open-end spinning apparatus is lined by a thin-walled insert (3) which exhibits a perforation for the discharge of material (dirt, fibers) from the interior space of the housing (1). For the protection of the edge (310) bounding this perforation downstream relative to the fiber flow, an edge protector (4) is provided which is slidable onto the edge (310) engaging over the latter. For sliding the edge protector (4) onto the edge (310) to be protected, or for stripping it therefrom, a combined insertion and ejection tool (5) is provided which is introducible into the insert (3) and movable with a contact surface (51) along the peripheral wall (33) of the insert (3). The combined insertion and ejection tool (5) has a receiving throat (6) for the temporary reception of the edge protector (4) with a step (60) overhanging the contact surface (51) and in turn exhibiting a stripping edge (67).

Protector device for an open-end spinning apparatus

An insert (3) is arranged in the interior space (10) of a housing (1) of an opening device for an open-end spinning apparatus. The insert (3) is of pot-like construction with a recess (35) provided in the base (34). The recess (35) exposes a bearing bore (18) through which a drive shaft extends for supporting the opening roller. A fixing device (41, 42) is likewise associated with the insert (3) securing its relative position to the housing. A guide element (5) introducible into the insert (3) is provided to guide the insert (3) during introduction into the housing (1) or during its removal. This has a contour corresponding to the interior space (10) of the housing (1) and one or more positioning lugs (50) on its end face opposite the base (34), corresponding to the number of the positioning cavities provided in the insert (3).
