Abstract
A cloth clamping chuck includes a pair of chuck jaws and a driving process that rotates at least one of the pair of chuck jaws around an open-close axis x to change an opening degree of the pair of chuck jaws. The cloth clamping chuck has a catching portion which is arranged in a position out of an extension line of the chuck jaws, and in associated with the pulling operation of cloth, is caught in a portion of the cloth other than the portion clamped by the pair of chuck jaws to deflect a force applied to the clamped portion of the cloth toward a side along the open-close axis.
Claims18
A cloth clamping chuck comprising
- a pair of chuck jaws, and
- a driving means that changes an opening degree of the pair of chuck jaws by rotating at least one of the pair of chuck jaws around an open-close axis, wherein
- the cloth clamping chuck is configured to conduct a pulling operation in an extending direction of the pair of chuck jaws after the pair of chuck jaws are closed to clamp cloth in a direction along the open-close axis,
- the cloth clamping chuck includes a catching portion that is offset from an extension line of the chuck jaw, the offset being along a direction parallel to the open-close axis, and
- in association with the pulling operation, the catching portion is configured to be caught on a portion of the cloth other than the portion clamped by the pair of chuck jaws to deflect a force applied to the clamped portion of the cloth toward the side along the open-close axis.
