Abstract: In a textile machine, in particular in a knitting machine, with controlla working elements and an arrangement for selecting the working elements, the working elements are held in their initial position by a holding magnet and are selectively released from their initial position by an electromagnetic control system. In order to obtain a textile machine with a simple design, capable of being driven at high working speeds but in a reliable and safe manner, at least one holding magnet is rigidly fixed to the part of the textile machine that carries the working elements. A direct contact between the working elements and the moving control system is thus avoided, so that a contactless selection of the working elements is made possible.

Abstract: In a flatbed knitting machine with electronic control and comprising programmable fixed-word stores and freely accessible stores, all the data for the operation of the machine is split into five divisions, namely motif pattern draft, needle set-up, knitting plan, function number schedule, and plan run. Data for the knitting of standard patterns, comprising the whole of the knitting plan division and part of the function number schedule division, is stored permanently in the fixed word stores. The stored data for the operation of the machine can be extracted and archived. Parts of the data of the divisions can be extracted to compose new patterns. Certain knitting courses can be suppressed and certain needle groups can be selected for adjustment without altering the already stored data. Information as to gauge can also be entered.

Abstract: In a flatbed knitting machine with electronic control and comprising programmable fixed-word stores and freely accessible stores, all the data for the operation of the machine is split into five divisions, namely motif pattern draft, needle set-up, knitting plan, function number schedule, and plan run. Data sub-groups from the needle set-up division, together with associated special function numbers for call-up, are stored in the fixed-word stores. Motif designs are created using the data stored in the divisions for needle set-up and plan run and by means of external selector switches on the machine. Facilities are provided for mirror-imaging and for suppression of part or all of a motif.

Abstract: A cloth draw-off roller for flat knitting machines has individual roller elements rotatably mounted on a draw-off shaft and intermediate rings arranged with axial play relative thereto between the roller elements, which intermediate rings are rigidly secured to the draw-off shaft and are resiliently connected to respect roller elements. In order to ensure mutually independent operation of the roller elements, means are provided which establish a minimum axial spacing between mutually facing surfaces of axially sequential intermediate rings, which spacing is larger than the axial spacing of the two faces of the respective roller element coming into contact with these surfaces.

Abstract: A flat knitting machine has a needle selection arrangement movable along needle bed, knitting needles arranged in needle channels of the needle bed and selector drivers or a tandem arrangement of working drivers and selector drivers adjoining the knitting needles in the needle channels, which cooperate with the needle selection arrangement. In order to achieve drivers of uniform weight with the same acceleration effect for differing gauges of the flat knitting machine, distance plates are fixed and inserted on at least one side of the drivers in the needle channels extending substantially along the length of the working drivers and/or selector drivers, the width of the distance plates being equal to the difference between the width of the needle channels and the width of the working drivers and/or selector drivers.

Abstract: In a method of determining and correcting the length of a piece of knitting eing produced on an electronically controlled flat knitting machine, the particular length of the piece of knitting which is being produced is continuously monitored by means of a sensor which supplies a value for the determined actual length to a control circuit where the value is compared with an instantaneous, programmed desired length value, and the determined real length value and the result of the comparison are used to control the stitch length in the following courses and/or the shape and/or type of knitting and pattern of the rest of the piece of knitting. by this means it is possible to produce constant-length pieces of knitting of the same shape, independently of changes in the technical knitting parameters, and controlled by the determination of the relevant actual knitted length of the piece of knitting.

Abstract: A flat knitting machine comprises flexible shank needles arranged in the dle channels of the needle bed, and, arranged behind these, jacquard jacks as well as a cam system which is movable over the needle bed and which comprises interengageable needle, jacquard and selection cam units which have fixed and shiftable cam elements. In order to create the possibility of selection for the flexible shank needles with sinkable needle butts, and in which the needle channel cutting is without interruption, i.e. can be produced with constant depth by one cutting pass, the flexible shank needles have an anterior first needle butt always projecting from the needle bed and a posterior second needle butt which sinks into the needle bed under the resilience of its own flexible shank.
