Abstract

Abstract Assembly in a double needle-row knitting machine for producing a plush-like surface structure includes a pair of knitting needle rows spaced from one another, a pair of knocking-over bars disposed adjacent the needle rows, respectively, within the space therebetween and spaced, in turn, from one another, the needle rows and the knocking-over bars being actuable for knitting respective individual webs located adjacent the respective knocking-over bars and connected by pile threads extending therebetween to form a base fabric web, the knocking-over bars having respective edges for firmly holding stitches knitted by the needles, and a severing device located in the space between the knocking-over bars directly below the edges of the knockingover bars for severing the pile threads to separate the individual webs.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 164 words
In a double needle-row knitting machine, an assembly for producing a plush-like surface structure comprising a pair of knitting needle rows spaced from one another, a pair of knockingover bars disposed adjacent said needle row, respectively, within said space therebetween, and spaced in turn, from one another, said needle rows and said knocking-over bars being actuable for knitting respective individual webs located adjacent the respective knocking-over bars and connected by pile threads extending therebetween to form a base fabric web, said knockingover bars having respective edges for firmly holding the stitches knitted by the needles, and a severing device located in the space between said knocking-over bars directly below said edges of said knocking-over bars for severing said pile threads to separate said individual webs, whereby said pile threads are severed just after being formed before the tension is relieved to provide for severance substantially at the middle of the pile threads and resulting in individual fabric webs of substantially the same pile height.
Claim 2
Dependent Claim 164 words
In a double needle-row knitting machine, an assembly for producing a plush-like surface structure comprising a pair of knitting needle rows spaced from one another, a pair of knockingover bars disposed adjacent said needle row, respectively, within said space therebetween, and spaced in turn, from one another, said needle rows and said knocking-over bars being actuable for knitting respective individual webs located adjacent the respective knocking-over bars and connected by pile threads extending therebetween to form a base fabric web, said knockingover bars having respective edges for firmly holding the stitches knitted by the needles, and a severing device located in the space between said knocking-over bars directly below said edges of said knocking-over bars for severing said pile threads to separate said individual webs, whereby said pile threads are severed just after being formed before the tension is relieved to provide for severance substantially at the middle of the pile threads and resulting in individual fabric webs of substantially the same pile height.
Claim 3
Dependent Claim 14 words
Assembly according to claim 1, wherein said severing device is a revolving band blade.
Claim 4
Dependent Claim 30 words
Assembly according to claim 2 including a guide member having a length corresponding to the width of the fabric web, said revolving band blade being supported by said guide member.
Claim 5
Dependent Claim 27 words
Assembly according to claim 3 wherein said guide member is constructed as a profile rod engageable through the individual webs of the fabric with the knocking-over bars.
