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.
Claims20
In an apparatus for coiling sliver or roving in a spinning can, comprising a rotary coiler plate having an outlet sliver guide, the improvement wherein an oscillatory motion equalizing the deposition density of said sliver or roving is superimposed on a rotary motion of said outlet sliver guide of said coiler plate caused by rotation of said coiler plate.
An apparatus for coiling a sliver or roving in a spinning can comprising:
- an approximately circular coiler plate mounted above said spinning can pivotable about an approximately centrally positioned pivot axis provided with a nonconcentric approximately circular opening;
- a drive for rotation of said coiler plate in one direction;
- an approximately circular outlet sliver guide comprising a disk positionable in said approximately circular opening of said coiler plate having an elongated recess on the bottom side of said disk which extends in the rotational direction of said coiler plate and a passage connecting said recess to the top side of said disk through which said sliver or roving can be fed, said disk being pivotally mounted about a pivot axis parallel to said centrally positioned pivot axis of said coiler plate;
- a square plate slidably mounted on a rigid frame for said apparatus for said coiler plate provided with an approximately circular hole for said coiler plate;
- a cam gear for providing an oscillating pivotal motion to said outlet sliver guide comprising a contacting roller positioned to engage the inner surface of said circular hole in said slidably mounted square plate rotatably mounted on a linear guided spring loaded mounting rod mounted on said coiler plate but engaging pivotally also said disk of said outlet sliver guide;
- and
- a guide drive comprising a piston cylinder for moving said square plate back and forth to provide said oscillating pivotal motion to said outlet sliver guide.
