False twisting apparatus

In a false twisting apparatus in which two endless belts are crossed while the surfaces of said two endless belts are brought into contact with each other and a yarn is nipped and false-twisted at the crossing point of said two endless belts, a method for setting the crossing angle of two brackets supporting rotatably said two endless belts comprising the step of adjusting the angle each bracket makes with the running direction of the yarn simultaneously and by the same amount.

In a false twisting apparatus comprising two endless belts arranged so that they are crossed while the surfaces of said endless belts are brought into contact with each other and a yarn is nipped and false-twisted at the crossing point of said two endless belts and brackets supporting rotatably said two endless belts, respectively and being supported on a shaft swingably with said shaft being as the center, a device for setting the crossing angle of the belts which comprises a block gauge having a shape of a trigonal prism, said block gauge being supported by a shaft parallel to the bracket-supporting shaft and including two faces bearing against the side faces of the crossed brackets, respectively.

In a false twisting apparatus comprising two endless belts arranged so that they are crossed while the surfaces of said endless belts are brought into contact with each other and a yarn is nipped and false-twisted at the crossing point of said two endless belts and brackets supporting rotatably said two endless belts, respectively and being supported on a shaft swingably with said shaft being as the center, a device for setting the crossing angle of the belts which comprises a block gauge having a shape of an eccentric column, said block gauge being supported by a shaft parallel to the bracket-supporting shaft and bearing against the side faces of the crossed brackets, respectively.

False twisting apparatus including a pair of endless belts intersecting centrally being driven in opposite directions with respect to the running direction of yarn passing between the belts at their point of intersection characterized by means for simultaneously adjusting the angle each belt makes with the direction of running of the yarn equally.

A false twisting apparatus comprising a pair of pulleys each having an axis of generation, the axis of generation of which are crossed so as to make equal predetermined angles with respect to the direction of run of yarn passing between an endless belt passing over each of the pulleys and engaged between the pulleys and a belt passing over each of the pulleys and intersecting at a point between the pulleys.
