Abstract: A flat-bed knitting machine is described which has a carriage apparatus movable along a needle bed apparatus, a front machine frame on which the needle bed apparatus is held and which includes at least one projecting part, and on each end a plurality of yarn eyes for supplying yarn to the needle bed apparatus. To make it possible to perform servicing and/or repair work on the underside, that is, in the cam area of the carriage apparatus without major effort or long stoppages, a protective cover receiving the plurality of yarn eyes is provided on one end of the needle bed apparatus, and this cover, when the machine is not in operation, is movable, along with the carriage apparatus contacting it on one side, by a predetermined displacement distance into an outer position in which the carriage apparatus is located partly on a projecting part of the front machine frame on the far side of the needle bed apparatus and there is freely accessible from below.

Abstract: A single or multi-cam system (11) for flat-bed knitting machines having needle, jack and selector cam units (13, 14 and 16) arranged one beneath the other is described. The needle cam unit (13) features at least one knitting cam and an integrated transfer cam (17, 18) for both carriage traverse and transfer directions. The knitting cam has adjustable, spaced apart, stitch cams (26, 27). The transfer cam has transfer cam parts having a pretensioning higher lobe (48, 49) for pretensioning the loops and a trailing lower lobe (51, 52) for transferring the loops and associated transfer receiving cam parts.With a multi-cam system (11) for flat-bed knitting machines of this type, the combined, respectively integrated knit and transfer cam (17, 18) is made narrower, without the additional cost or effort associated with mechanical drives and/or switching devices being necessary.

Abstract: An electromagnetically-controlled flat knitting machine has a supervising system for checking the functional readiness of a setting magnet of the machine. The supervising system comprises a microprocessor with a detecting and signalling device, and a detector for measuring closed and open circuits. Such measurements are collected periodically from the microprocessor through an intermediate unit and are signalled on the signalling device. The individual setting magnets can be checked for functional readiness both in the case of a stationary as well as a running machine without these having to be specially actuated (i.e. energized) for this purpose. To this end, a direct voltage of an intensity less than the response voltage of the winding thereof is applied to the setting magnet concerned.

Abstract: A carriage 14 is reciprocable along a needle bed of a flat knitting machine and carries a needle cam. A pair of stitch cams 12 and 13 are adjustably supported by the carriage 14 and are disposed so as to trail behind the needle cam in alternate strokes of the carriage, respectively. An adjustment mechanism 11 includes a stepping motor 38 (FIG. 3) which adjusts the trailing stitch cam 12 or 13 not only at the beginning of the respective stroke but also during the course of the stroke itself, thereby enabling the stitch density to be varied within each row of the knitted article as well as from row to row.

Abstract: In a fabric take-down mechanism for a flat knitting machine provided with stitch strippers, the edge of the fabric disposed in front of the stitch strippers is engaged by a plurality of take-down hooks (27) of a hook bar (28) located beneath the comb gap (13) defined by the ends of the needle beds (10 and 11). The engagement of the fabric edge is produced by a free fall of the take-down hooks (27) over a limited initial length of take-down travel (A). The take-down of the fabric by the take-down hooks (27) is effected synchronously with the movement of a succeeding take-down roller (13) in the effective area of which the edge of the fabric is carried by means of the take-down hooks (27).

Abstract: Described is a high-flex insulated electrical cable (11) for the carriages of flat knitting machines, this cable having two concentric multi-strand twisted layers (12, 13) each of which is comprised of a plurality of insulated individual strands (17) laid in long lay at the same twist angle.To enable a cable (11) of this nature to resist torsional stresses to an increased degree while retaining its shape and also to give it an extended length of life despite such torsional stresses, the individual strands (17) of each layer (12, 13) have an outer peripheral layer of resiliently deformable soft plastic (18, 19) injected therearound which penetrates into the gussets (22) which are formed between the individual strands (17).
