Device for winding of yarn packages
First Claim
1. In a textile bobbin winding machine, a device for winding yarn packages at a work station of the winding machine, the improvement comprising:
- a motor including a stator and a rotor,a bobbin winder work station housing having a recess formed therein, said recess having said stator received and retained therein,a friction roller assembly comprising a shaft and a friction roller removably mounted on said shaft for surface driving of yarn packages during winding thereof, one end of said shaft extending axially from said friction roller into said recess in said bobbin winder work station housing, said shaft being mounted directly to said rotor, andmeans disposed within said bobbin winder workstation housing for radially mounting said shaft to rotatably support said shaft.

Abstract
At each work station of a textile machine producing wound bobbins, the yarn package on which yarn is wound is driven by a friction roller. In contrast to the conventional driving of the roller by a gear motor flanged to the housing of the work station, which has the disadvantage of requiring space and difficulty in removing and replacing the friction roller for maintenance, the present invention simplifies the friction roller drive by configuring the housing of the work station for the direct reception of the stator windings of the drive motor for the friction roller and mounting the friction roller and the rotor of the drive motor together on a continuous shaft.

10. In a textile bobbin winding machine, a device for winding of yarn packages at a work station of the winding machine, the improvement comprising:
-
a motor including a stator and a rotor, a bobbin winder work station housing defining a shaft-supporting opening therethrough and a stator-receiving recess surrounding said opening at one side thereof, having said stator received and retained therein, a removable cover for mounting to said one side of said bobbin winder work station housing for enclosing said recess, a friction roller assembly comprising a shaft and a friction roller removably mounted on said shaft for surface driving of yarn packages during winding thereof, one end of said shaft extending axially from said friction roller to be rotatably supported within said opening of said bobbin winder work station housing, said rotor being disposed coaxial with said opening and mounted directly to said shaft within said stator, said shaft extending axially through said opening, and wherein when said cover is removed from said one side of said bobbin winder work station housing and when said friction roller is removed from said shaft, said shaft and said rotor can be axially withdrawn as a unit from said one side of said bobbin winder work station housing.
