Abstract
A flat bed knitting machine with at least one carriage mounted to a needle bed. A yarn changing device is capable of picking yarn guide collars from collar support racks located at both ends of the needle bed. Each collar rack is designed to hold a plurality of yarn guide collars. The yarn changing device includes a collar support mechanism carried by the carriage for detachably holding a selected one of the collars. The collar support mechanism has three working positions including an operational position and two transfer positions. Each transfer position allows the transfer of the selected collar between the collar support mechanism and one of the support racks. A mechanism is also provided to change the position of the collar support in response to movements of the carriage relative to the needle bed. In a preferred embodiment, the position changing mechanism changes the position of the collar support mechanism in response to movements of the carriage relative to the needle bed.
