Abstract
Knot catcher for yarns and threads includes two rotary rollers spaced from each other to form therebetween a thread-receiving through opening which is limited at two ends thereof by two opposite walls of the housing of the knot catcher. The size of the opening can be adjusted by adjusting the rollers relative each other.
Claims15
A knot catcher for yarns and threads, comprising two elements adjustable relative to each other and forming between each other a thread-receiving through opening, said elements being two rotation-symmetrical bodies of which at least one is rotationally supported and at least one is adjustable relative to the other rotation-symmetrical body to adjust a size of said through opening for insertion of a thread thereinto, said two rotation-symmetrical bodies having cylindrical peripheral surfaces which form said through opening, rotation axles and two end flanges, said two end flanges providing wall means extending perpendicular to said axles and limiting said through opening at two ends thereof.
A knot catcher for yarns and threads, comprising:
- two rotation-symmetrical bodies having cylindrical peripheral surfaces and rotation axles, said rotation-symmetrical bodies forming a thread-receiving through opening therebetween, at least one of said rotation-symmetrical bodies being rotationally supported and at least one of said rotational symmetrical bodies being adjustable relative to another of said rotation-symmetrical bodies to adjust a size of said through opening for insertion of a thread therein, and
- a housing having two opposite walls extending substantially perpendicular to said axles and limiting said through opening at two ends thereof, said rotation-symmetrical bodies being supported between said opposite walls of said housing, one of said opposite walls along with one of said bodies supported thereon being pivotable so that, when a knot which is larger than said through opening reaches said through opening, said front wall is pivoted to send an actuating signal for automatic control of thread processing.
A knot catcher for yarns and threads, comprising two elements adjustable relative to each other and forming between each other a thread-receiving through opening, said elements being two rotation-symmetrical bodies of which at least one is rotationally supported and at least one is adjustable relative to the other rotation-symmetrical body to adjust a size of said through opening for insertion of a thread thereinto, said two rotation-symmetrical bodies having cylindrical peripheral surfaces which form said through opening and rotation axles;
- and a housing including two opposite parallel flat walls between which said rotation-symmetrical are supported so as to be adjustable relative to each other.
