IPC: B23Q3/00
Filed: 2004-10-04
Abstract: A positioning device, wherein a plug member (12) inserted into a positioning hole (5) formed in a second block is projected from a first block. A plurality of slide portions (61) opposed to each other on both sides of the plug member (12) are disposed on the plug member (12) in the state of being movable in a first radial direction (D1) generally orthogonal to the opposed direction. A first pressing member (15) and a second pressing member (19) are disposed on the outsides of the slide portions (61) so as to be expandable and contractible in the radial direction and movable in the axial direction. Since the first pressing member (15) is driven in the base end direction by a drive means, the slide portions (61) expand the first pressing member (15) in the radial direction through the second pressing member (19) to move the slide portions (61) in the first radial direction (D1) relative to the plug member (12).

Title: Yarn feeding device of weft knitting machine
Inventor: MORITA TOSHIAKI
IPC: D04B15/48
Filed: 2004-10-15
Abstract: A yarn feeding device of a weft knitting machine capable of preventing knitting yarns from being loosened even if the position of a carrier supplying the knitting yarns at a knitting end. A carriage (4) which completes one course of knitting to the knitting end of a knitting fabric (2) is stopped as shown by a solid line. Knitting in a next course is performed when the carriage (4) inverses its moving direction and re-starts its movement. As shown by chain-double dashed lines, since the knitting yarns (7) are not knitted to the knitting fabric (2) until a carrier (5) entrained by the carriage (4) reaches the position of a knitting needle holding the stitch of the knitting fabric (2) at the knitting end, the knitting yarns (7) present in a supply route between a yarn supply mechanism (8) and the carrier (5) are excessively increased and loosened. Since a distance between a yarn supply port (6) formed at the tip of the carrier (5) and the knitting needle at the knitting end of the knitting fabric (2) is also reduced, the knitting yarns (7) are further increased excessively. The further excessively increased knitting yarns (7) are taken in by a yarn supply means (16) by reversely rotating a servo motor (22), and further pulled in by an unwinding arm (17) to absorb the looseness.
