Abstract
A cam system for flat-bed knitting machines is provided with a needle cam unit which has at least one knitting cam and a transfer cam, integrated therein, for both carriage travel and transfer directions. The knitting cam has adjustable needle sinkers and a knitting cam/knitting element that projects the needles for knitting, and the transfer cam has at least one delivery transfer element and an associated receiving transfer element. The needles, which are supported in needle tracks of the needle beds, are controlled by intermediate jacks embodied as pressure elements, the pressure feet of which can be moved along various courses, which are located in the planes of pressure bars. In order to be able to perform combined loop formation and loop transfer in a single cam unit in a single operation, using a single needle, in such a cam system, the knitting cam/knitting element simultaneously embodies the receiving transfer element of the transfer cam. Four different courses or planes of pressure bars are provided; the first of these effects the delivery transfer movement, the second the loop formation and/or loop receiving movement, the third the tuck position, and the fourth the non-wo…
