A patterning device employs an elongated strip which is fixed between an operating element, such as a guide bar of a warp knitting machine, and a fixed support point. In addition, the patterning device has a displacing element in the form of a rotatable eccentric or a reciprocally mounted roller which is used to deflect the strip between two points intermediately of the length of the strip so as to exert a pulling force on the guide bar. The amount of deflection of the strip determines the amount of movement of the guide bar. The guide bar can be returned by way of a spring or by a second strip which is deflected in similar manner as the first strip by a displacing element. In one embodiment, a single displacing element is used for deflecting purposes while in other embodiments, a multiplicity of displacing elements are used. The strips may be attached directly to the guide bar or indirectly, for example, over a pivotally mounted lever.
The combination of at least one operating element of a textile machine and a patterning device for moving said operating element, said patterning device including an elongated flexible pull element secured to said operating element and at least one displacing element for selectively varying the effective length of said pull element relative to said operating element, said pull element being partially engaged with said displacing element at least during a displacing operation.
A patterning device for moving an operating element of a textile machine, said patterning device including an elongated flexible pull element secured to said operating element at one end and to a fixed point at an opposite end, and at least one displacing element for selectively varying the effective length of said pull element relative to said operating element, said pull element being partially engaged with said displacing element at least during a displacing operation.
The combination of at least on operating element of a textile machine and a patterning device for moving said operating element, said patterning device including an elongated pull element secured to said operating element and at least one displacing element for selectively varying the effective length of said pull element relative to said operating element, said displacing element being mounted for rectilinear movement to vary said effective length of said pull element.
The combination of at least one operating element of a textile machine and a patterning device for moving said operating element, said patterning device including an elongated strip secured to said operating element, a plurality of displacing elements disposed in a row along said strip for selectively varying the effective length of said pull element relative to said operating element and a plurality of rollers in engagement with said strip on a side opposite from said displacing elements, said rollers being disposed in alternating relation with said displacing elements.
The combination of at least one operating element of a textile machine and a patterning device for moving said operating element, said patterning device including an elongated pull element secured to said operating element and a plurality of displacing elements disposed along said pull element in a pulley block arrangement for selectively varying the effective length of said pull element relative to said operating element.
The combination of at least one operating element of a textile machine and a patterning device for moving said operating element, said patterning device including an elongated pull element secured to said operating element and a plurality of displacing elements disposed in a row along said pull element with some of said displacing elements engaging said pull element with an angle of 180.degree. and with the remainder of said displacing elements engaging said pull element with an angle less than 180.degree. for selectively varying the effective length of said pull element relative to said operating element.
The combination of at least one operating element of a textile machine and a patterning device for moving said operating element, said patterning device including an elongated pull element secured to said operating element and at least one displacing element for selectively varying the effective length of said pull element relative to said operating element, said displacing element including a rotatable eccentric and a ring rotatably mounted relative to said eccentric, said ring being disposed in stationary contact with said pull element.
The combination of at least one operating element of a textile machine and a patterning device for moving said operating element, said patterning device including an elongated pull element secured to said operating element, at least one displacing element for selectively varying the effective length of said pull element relative to said operating element, and a pivotally mounted lever secured at an intermediate position to said pull element and at a free end thereof to said pull element.
A patterning device for moving an operating element of a textile machine, said patterning device including an elongated pull element secured to said operating element at one end and to a fixed point at an opposite end, and a plurality of displacing elements along said pull element for selectively varying the effective length of said pull element relative to said operating element, each said displacing element being mounted for rectiliner movement to vary said effective length of said pull element.
