Abstract: Empty and full containers are moved from and to a spinning apparatus having an input side having a waiting station for a full container, a working station for a container from which filament is withdrawn, and a takeoff station for an emptied container and an output side having a waiting station for an empty container, a working station where a container is filled with spun filament, and a takeoff station for full containers awaiting transport away. A sensor monitors the fullness of the container or containers at the input-side working station and generates an input-side working-station priority signal when the respective container is nearly empty and another sensor monitors the fullness of the container or containers at the output-side working station and generates an output-side working-station priority signal when the respective container is nearly full.

Abstract: A coiler plate of the type adapted for rotational disposition in association with a sliver can of a textile draw frame, wherein the coiler plate has a compression surface for contact with sliver deposited in the can and a sliver conduit through the coiler plate opening at the compression surface, may be coated with enamel over the compression surface and the interior wall surfaces defining the sliver conduit to provide a reduced coefficient of friction relative to sliver.

Abstract: Full sliver cans are positioned in readiness for replacing cans being emptied with an end of the sliver exposed from the full can. A movable carriage is positioned at a full can and a gripper on the carriage extending vertically downward is rotated around the can to grasp the exposed end with suction. Any excess length of sliver is severed. The gripper is then raised to lift the sliver end and the gripper is pivoted in its raised position above a feed table onto which the gripper releases the sliver end for feeding on the table to the draw frame with the other slivers thereon. The full can whose sliver end is on the feed table is then pushed from the ready position into the sliver feed position and in doing so pushes the empty can out of sliver feed position to complete the replacement.

Abstract: The apparatus which coils a plurality of turns of sliver or roving for example from a spinning machine in a spinning can comprises a coiler plate having an outlet yarn piece guide. To equalize the deposition density of the sliver or roving an oscillatory motion is superimposed on the motion of the outlet sliver guide of the coiler plate caused by the rotation of the coiler plate.

Abstract: A method and apparatus for changing bobbins in a flyer spinning frame which includes a bobbin rail for supporting bobbins adjacent the flyers movable both vertically and tiltably, the bobbin rail being moved sequentially from an upper bobbin winding position, a lower horizontal position, a forwardly tipped position, then upwardly in the tilted position into a comfortable bobbin doffing position, downwardly into the lower position, back into a horizontal position while in the lower position then finally upwardly into the upper bobbin winding position.
