Abstract
The method for separating doubled yarns comprises moving forward a clamper which is opened and closed in a manner of a pair of scissors in an open state forward two yarns arranged in a pulled form, positioning said pulled yarns into an opening of the clamper and thereafter closing the opening, clamping one yarn positioned deep in the opening more strongly than the other, and moving backward the clamper to thereby separate the strongly clamped yarn from the other while clamping the strongly clamped yarn.
Claims7
A method for separating doubled yarns comprising the steps of:
- moving a clamper in a first direction toward two yarns arranged in a parallel form, wherein the clamper can be opened and closed in a scissor-like fashion,
- positioning the two yarns into an opening of the clamper and thereafter closing the opening to thereby clamp the two yarns in the clamper, wherein one of the two yarns is positioned deeper in the opening than the other of the two yarns,
- clamping the yarn positioned deeper in the opening more strongly than the other, and
- moving the clamper in a second direction in order to separate the two yarns, wherein the yarn positioned deeper in the opening is maintained in a clamped position in the clamper and the other of the two yarns is released from the clamper.
A device for separating a ply yarn including at least first and second doubled yarns, comprising:
- a pivotal arm,
- clamp means mounted at an end of the pivotal arm, the clamp means including two fixed plates having substantially the same shape and a movable plate movably held between the two fixed plates and being supported by a shaft, the movable plate being movable with respect to the two fixed plate in a scissor-like fashion, thereby enabling the clamp means to clamp yarn between the movable plate and the two fixed plates,
- moving means for moving the movable plate, and
- driving means for driving the pivotal arm such that the clamp means moves in first and second directions, wherein the clamp means is moved in the first direction to clamp the first and second yarns and is moved in the second direction to separate the first and second yarns such that the first yarn is held by the clamp means and the second yarn is released from the clamp means.
