In order to switching yarns used for knitting by switching a plurality of yarn feeders, a knitting member switching apparatus is provided. The knitting member switching apparatus includes a plurality of holders provided on a side of a carriage, a stopping device provided on an end portion such as a left side end on a needle bed. The stopping device includes a plurality of stopping stands and switching mechanisms in correspondence with the holders, and is further provided with a control device for letting the carriages travel and for selecting knitting needles based on knitting data.

Removable moving member for knitting and weft knitting machine provided with knitting member switching apparatus

A yarn feeder can be stopped at a stopping mechanism and attached to and detached from a holder. The holder is fitted to a front end of a holding arm. The carriage-side holding arm is held by a moving member holding mechanism. The moving member holding mechanism includes a bringing state switching mechanism to switch the bringing state of the moving member by the carriage. The bringing state switching mechanism acts on a coupling portion on the carriage side, and can shift the bringing position of the moving member holding mechanism relative to the carriage and perform the switching to a position where the moving member holding mechanism is not brought. A rail is provided such that the yarn feeder's position does not change even when the moving member holding mechanism is separated from the carriage. The rail is installed to be parallel with a needle bed's longitudinal direction.

Weft knitting machine capable of switching moving member bringing state

A permanent magnet applies first sliding resistance in-between a holding arm and a guide rail. A carriage is provided with an electromagnet for magnetically applying second sliding resistance in-between the holding arm and the carriage. Although the holding arm persists in moving through inertia when the carriage stops movement, a sliding resistance that is the sum of the first sliding resistance and the second sliding resistance acts on the holding arm, and it is possible to promptly stop. Since the second sliding resistance does not act when the carriage brings the holding member, it is possible to reduce a load. When the carriage starts bringing the holding arm, a difference between the first sliding resistance and the second sliding resistance becomes the sliding resistance, and it is possible to decrease sliding resistance that acts when bringing is started, and reduce occurrence of an impact and a noise.
