Abstract
A knitting machine has a bed, knitting implements which are mounted displaceably in the bed and which each have at least an operating and a pivotably first control butt, and at least one patterning arrangement which has a cam portion intended for guiding the butts, with at least one respective non-knitting, tuck and knitting track formed by cam member, and a selector intended for pivoting the control butts, by means of which the butts are distributed to a respective one of said tracks. The selector has a first control unit for controlling selected knitting implements into the non-knitting track and a second control unit for selectively distributing the other knitting implements to the tuck or knitting track.
Claims21
A knitting machine, comprising a bed;
- a plurality of knitting implements mounted displaceably in said bed and each having at least one operating butt and at least one first movable control butt;
- and a pattering arrangement for being passed by said knitting implements and including a cam and selector means, said cam including cam members defining respective knitting, tuck and non-knitting tracks for each of said operating and control butts, said tracks being disposed in superposed relationship and containing a first tuck track cooperating with said operating butts and having a first raising portion leading into a tuck position and a first knitting track cooperating with said first control butts, having a second raising portion leading into a knitting position and being substantially parallel to said first raising portion, said selector means including first control means and second control means, said first control means serving for selectively guiding said first control butts onto said second raising portion or into said non-knitting track, and said second control means being disposed in a region of said second raising portion and serving for selectively leaving said first control butts on said second raising portion or guiding said first control butts into said tuck track.
A knitting machine, comprising a bed;
- a plurality of knitting implements mounted displaceably in said bed and each having at least one operating butt and at least one first movable control butt;
- and a pattering arrangement for being passed by said knitting implements and including a cam and selector means, said cam including cam members defining respective knitting, tuck and non-knitting tracks for each of said operating and control butts, said tracks being disposed in superposed relationship and containing a first tuck track cooperating with said operating butts and having a first raising portion leading into a tuck position and a first knitting track cooperating with said first control butts, having a second raising portion leading into a knitting position and being substantially parallel to said first raising portion, said selector means including first control means and second control means, said first control means serving for selectively guiding said first control butts onto said second raising portion or into said non-knitting track, and said second control means being disposed in a region of said second raising portion and serving for selectively leaving said first control butts on said second raising portion or guiding said first control butts into said tuck track, said patterning arrangement comprising a further cam member with a first drawing-down portion which acts on said operating butts and which is provided with a stitch-forming edge for establishing a drawing-down depth of said knitting implements;
- and a counter-cam member associated with said stitch-forming edge and having an inclined run-in portion, said run-in portion being designed for gently catching said operating butts of said knitting implements which are guided by one of the two drawing-down portion.
A knitting machine, comprising a bed;
- a plurality of knitting implements mounted displaceably in said bed and each having at least one operating butt and at least one first movable control butt;
- and a pattering arrangement for being passed by said knitting implements and including a cam and selector means, said cam including cam members defining respective knitting, tuck and non-knitting tracks for each of said operating and control butts, said tracks being disposed in superposed relationship and containing a first tuck track cooperating with said operating butts and having a first raising portion leading into a tuck position and a first knitting track cooperating with said first control butts, having a second raising portion leading into a knitting position and being substantially parallel to said first raising portion, said selector means including first control means and second control means, said first control means serving for selectively guiding said first control butts onto said second raising portion or into said non-knitting track, and said second control means being disposed in a region of said second raising portion and serving for selectively leaving said first control butts on said second raising portion or guiding said first control butts into said tuck track, said patterning arrangement comprising a further cam member with a first drawing-down portion which acts on said opening butts and which is provided with a stitch-forming edge for establishing a drawing-down depth of said knitting implements, said defining member having a positioning cam which is arranged at an end of said separating cam member and which pivots said second control butts back and thereby pivots said first control butts forward, another of said cam members which extends parallel to said drawing-down portion and which acts on said first control butts having a top side provided with a recess disposed in the region of said positioning cam, and during a drawing-down phase said knitting implements which are raised into a tuck position being positively guided until they leave said positioning cam with their operating butts between said drawing-down portion and said separating cam member and after leaving said positioning cam they are positively guided with their operating butts at said drawing-down portion and with their first control butts at said top side.
