Abstract
Abstract The device includes a fixed separating member with two mutually parallel thread guide plates spaced from one another and a cutting body movable toward the fixed member and operable by a textile machine. The cutting body includes two clamping shanks, which in the course of a cutting motion slide against the outer surfaces of the guide plates with a predetermined contact pressure in order to tension a thread guided crosswise over the guide plates. The cutting body also includes a blade so arranged between and parallel to the clamping shanks that in the direction of the cutting motion its cutting edge lies behind the clamping edges of the clamping shanks.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
A thread parting device for textile machines, comprising: a fixed, separating member, comprising two mutually parallel thread guide plates spaced from each other; a cutting edge-containing cutting body movable toward said fixed separating member and operable by means of said textile machine, comprising a U-shaped thread tensioning bow having two spring clamping shanks which during the course of a cutting motion of said device are slideable against the outer surfaces of said thread guide plates with a predetermined contact pressure in order to tension a thread guided crosswise over the thread guide plates, and a blade so arranged on said cutting member between and parallel to said clamping shanks that in the direction of the cutting motion its cutting edge lies behind said clamping edges of said spring clamping shank.
Claim 2
Dependent Claim
130 words
A thread parting device for textile machines, comprising: a fixed, separating member, comprising two mutually parallel thread guide plates spaced from each other; a cutting edge-containing cutting body movable toward said fixed separating member and operable by means of said textile machine, comprising a U-shaped thread tensioning bow having two spring clamping shanks which during the course of a cutting motion of said device are slideable against the outer surfaces of said thread guide plates with a predetermined contact pressure in order to tension a thread guided crosswise over the thread guide plates, and a blade so arranged on said cutting member between and parallel to said clamping shanks that in the direction of the cutting motion its cutting edge lies behind said clamping edges of said spring clamping shank.
Claim 3
Dependent Claim
23 words
