Fibre guide insert for an opening roller housing

Abstract

A fibre guide insert for an opening roller housing, with an insert body to be pushed into a mounting opening of the opening roller housing, the insert body having a fibre guide surface forming a fibre channel inlet and a fibre channel connection section connected to a fibre channel input. An opening roller housing for an opening device of an open-end rotor spinning device, having a fibre channel leading into an opening roller housing interior, where it adjoins a fibre channel input for fibres, and a mounting opening for a fibre guide insert, which mounting opening is open towards the opening roller housing interior. In order to provide a fibre guide insert for an opening roller housing, which provides a suitable fibre channel inlet area in a simple way according to the fibres to be processed, there is provision for the fibre channel connection section to be formed on an end face of the insert body and the fibre guide surface running in the direction of the longitudinal axis of the insert body to adjoin the fibre channel connection section. In order to provide an opening roller housing, of which the fibre guide surface adjoining the fibre channel is easily adapted to the specific application, there is provision for the mounting opening to run parallel to the tangent of an opening roller arranged in the opening roller housing interior and the mounting opening to be configured in such a way that an insert body of a fibre guide unit to be pushed into the mounting opening is connected to the fibre channel input with a fibre channel connection section arranged on the insert body on the end face, in which case the insert body is pushed into the mounting opening via an outer opening of the opening roller housing.

1 . A fibre guide insert for an opening roller housing, the fibre guide insert comprising:
 an insert body to be pushed into a mounting opening of the opening roller housing, the insert body having a fibre guide surface forming a fibre channel inlet and a fibre channel connection section connected to a fibre channel input,   characterised in that the fibre channel connection section is formed on an end face of the insert body, and the fibre guide surface running in a direction of the longitudinal axis of the insert body adjoins the fibre channel connection section.   
     
     
         2 . The fibre guide insert according to  claim 1 , characterised in that the fibre channel connection section runs perpendicularly to the longitudinal axis of the insert body. 
     
     
         3 . The fibre guide insert according to  claim 1 , characterised in that the fibre channel connection section runs at an angle to the longitudinal axis of the insert body. 
     
     
         4 . The fibre guide insert according to  claim 1 , characterised in that the insert body has a guide element on its peripheral surface to be brought into engagement with a guide element mount of the mounting opening. 
     
     
         5 . The fibre guide insert according to  claim 4 , characterised in that the guide element is formed by a projection, a groove, a flattening, or a combination which extends in the direction of the longitudinal axis of the insert body. 
     
     
         6 . The fibre guide insert according to  claim 1 , characterised in that the insert body has a fastening for fixing the insert body in the mounting opening. 
     
     
         7 . The fibre guide insert according to  claim 6 , characterised in that the fastening is formed by a magnetic element arranged on the insert body. 
     
     
         8 . The fibre guide insert according to  claim 1 , characterised in that the insert body has a colour coding adapted to the length of the fibre guide surface. 
     
     
         9 . An opening roller housing for an opening device of an open-end rotor spinning device, having a fibre channel leading into an opening roller housing interior adjoining a fibre channel input for fibres, and a mounting opening for a fibre guide insert, the mounting opening being open towards the opening roller housing interior,
 characterised in that   the longitudinal axis of the mounting opening runs parallel to a tangent of an opening roller arranged in the opening roller housing interior and the mounting opening is configured in such a way that an insert body of a fibre guide unit to be pushed into the mounting opening is connected to the fibre channel input with a fibre channel connection section arranged on the insert body on the end face, in which case the insert body is pushed into the mounting opening via an outer opening of the opening roller housing.   
     
     
         10 . The opening roller housing according to  claim 9 , characterised in that the outer opening is configured in such a way that an insert body of a fibre guide unit is pushed in parallel to a tangent of an opening roller arranged in the opening roller housing interior or radially to an opening roller arranged in the opening roller housing interior or along an overlap of both directions.
