Abstract
A machine for producing a knitted fabric having a knitted ground material of a ground thread and a pile or loop-pile surface from additional pile threads or fibers, the machine having a plurality of individually selectable knitting elements and at least two knitting systems, each with a feeding position for the ground thread and the pile thread or a fiber web. A patterning mechanism is provided at each knitting system for selecting the particular knitting element which is to process the pile threads or fibers in that system and each knitting element having a knitting cam segment to produce the stitches.
Claims11
In a machine for producing knitgoods including a ground fabric, knitted from a ground thread, and a pile or plush layer, consisting of pile threads or fibers, the machine having a plurality of individually selectable knitting elements and at least one group of at least two successive knitting systems, each knitting system comprising:
- a patterning mechanism for selecting said knitting elements;
- and only one means for feeding a pile thread or pile fibers to said selected knitting elements, said means for feeding consisting of feeding means for feeding a pile thread or pile fibers of one property to said selected knitting elements;
- a feeding means for feeding said ground thread;
- a knitting cam to produce stitches with said ground thread and said pile thread or fibers by acting on said selected knitting elements;
- and means for selectively moving said knitting cam to at least a knitting position and to a non knitting position, wherein only the knitting cam of the last knitting system of said group is moved to said knitting position whereas the knitting cams of all preceding systems of said group are moved to said non knitting position, such that the knitting elements selected in a preceding system of said group pass all said preceding systems without producing stitches whereas said knitting cam of said last knitting system acts on the knitting elements selected in any system of said group for producing stitches.
In a machine for producing knitgoods including a ground fabric, knitted from a ground thread, and a pile or plush layer, consisting of pile threads or fibers, said machine having a plurality of individually selectable knitting elements and at least one group of at least two successive knitting systems, each knitting system comprising:
- a patterning mechanism for selecting said knitting elements;
- and only one feeding means for feeding a pile thread or pile fibers of one property to said selected knitting elements;
- a feeding means for feeding said ground thread;
- a knitting cam to produce stitches with said ground thread and said pile thread or fibers by acting on said selected knitting elements;
- and means for selectively moving said knitting cam to at least a knitting position and to a non knitting position, wherein only the knitting cam of the last knitting system of said group is moved to said knitting position whereas the knitting cams of all preceding systems of said group are moved to said non knitting position, such that the knitting elements selected in a preceding system of said group pass all said preceding systems without producing stitches whereas said knitting cam of said last knitting system acts on the knitting elements selected in any system of said group for producing stitches;
- wherein said moving means includes a first slide to which said knitting cam is attached and means for displacing said first slide at least to said one knitting position and to said non knitting position;
- wherein said first slide includes a recess, and comprises a rotatable cam disposed in said recess for altering the stitch length by moving said first slide by said rotatable cam;
- and further comprising
- a lever biased by a spring for holding said rotatable cam in the recess of said first slide.
A method for producing a knitted fabric, including a ground fabric knitted from a ground thread, and a plush or pile layer, consisting of pile threads or fibers having different properties, on a circular knitting machine having knitting needles and a plurality of successive systems, each system having a feeding means for feeding said ground thread, one feeding means for feeding one of said pile threads or fibers of one property, a knitting cam to produce stitches with said ground thread and said one pile thread or fibers, and means for selectively moving said knitting cam to at least a knitting position and to a non knitting position, said method comprising the steps of at first laying only one of said pile threads or fibers with a selected one of a plurality of selectable properties into the hooks of selected ones of said knitting needles at each of so many successive knitting systems as there are selectable properties;
- laying only in the last of these knitting systems, also the ground thread into the hooks of all selected knitting needles;
- and forming stitches on all selected knitting needles only in said last knitting system by moving said knitting cams of the other of said successive knitting systems to said non knitting position and leaving only the knitting cam of said last knitting system in said knitting position.
