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. Behind each flexible shank needle there is provided a displaceable arresting jack having an arresting jack butt as well as a coupling portion at its forward end for coupling to the flexible shank of the flexible shank needle and for simultaneously lifting the second needle butt from the needle bed. Behind the arresting jack there is displaceably mounted a jacquard jack which has a first, operating butt and a second, selection butt. In the needle cam unit, at least in the region of the second needle butt, and symmetrically arranged with respect to the central longitudinal axis of the cam system, there are provided two needle sinkers displaceable in the plane of the cam system and two cam units shiftable into and out of the plane of the cam system for extending the needles in the formation of stitches.
Abstract:
In the needle selection device on a knitting machine there are provided knitting needles and jacks arranged to be displaceable in needle channels, and flexible selection shanks with operating butts mounted on the knitting needles or jacks. The selection shanks can be lowered in the needle channels by pressure cam elements moved over the needle channels, and selection elements are also provided controlled selectively by selection magnets and moved over the needle channels. In order to achieve a structure for the device which is mechanically structurally simple, displaceable selection jacks with selection butts are arranged in the needle channels to engage above or below the flexible selection shanks, the selection elements are double-armed pivotable selection flaps with inclined contact surfaces for the displacement of the selection jacks, and the selection magnets are flap-anchoring magnets or solenoids whose armatures when energized hold the selection flaps in the vertical position for forward displacement of the selection jacks.
Abstract:
Knitting machine with a needle bed in which knitting tools having projections are mounted for raising and lowering, with a cam unit which can be transported past the projections and which has at least one lowering cam acting on the projections of the knitting tools which is adjustable with regard to its lowering depth, on which a runner is movably fastened having a plurality of pathways interacting according to pattern with the runner during the carrying of the cam unit past the projections of the knitting tools for the adjustment of the lowering cam to a preselected lowering depth, and with a controller acting before each passage of the cam unit past the feet of the knitting tools for the shifting of the runner to the position required for the interaction with a selected pathway (FIG. 7).
Abstract:
The carriage of a flat bed knitting machine is provided with Hall effect devices at locations in close proximity to a steel needle bed and as the carriage is moved along the bed, one or another of the devices produces an output signal each time it passes over a steel segment separating slots in the bed.
Abstract:
A racking mechanism for a circular knitting machine includes at least four pawls drivable in succession in synchronization with needle cylinder movement on the knitting machine, and an evenly cut rack wheel which may be attached to a pattern drum of the knitting machine with elements to cause the pawls to selectively engage the rackwheel and to rack the pattern drum as and when required during a racking sequence.In a particular embodiment, the racking mechanism includes a device to enable all pawls to be bluffed outside a racking sequence which device can be triggered to unbluff from a timing chain stud and can be operated to bluff at the end of a sequence by a cam piece on the rackwheel.
Abstract:
A hand knitting machine having a needle bed, a series of sinkers extending from the front edge of the needle bed, a series of corresponding number of latch needles alternated with the sinkers, an actuator movably supported on the needle bed, and needle selecting means. The needle selecting means has a central sinker on the actuator and at either side of the sinker a selecting cam having a duplicatedly inclined acting cam face inwardly backwardly of the actuator. The needle selecting means further has a control means to selectively restrain the needles from being subject to the selecting cam, whereby all the needle are divided into two groups each time the actuator travels in either direction on the needle bed.
Abstract:
Described herein is a weft-knitted spacer fabric and a preparation method thereof, a polyurethane foam composite material including the fabric, a preparation method of the composite material and its use in shoe materials. The weft-knitted spacer fabric consists of an upper surface layer, intermediate spacer yarns, and a lower surface layer, and the upper surface and the lower surface layer are connected by the tuck of the spacer yarns in the upper surface and the lower surface layer to form a three-dimensional structure in an integrated manner. The different selected tuck needle changes the connecting distance and the number of connections of the tuck, and the thickness of the spacer fabric and the arrangement density of the spacer yarns are changed by the action of the upper and lower surface layers of elastic yarns.
