Abstract
In an open-end spinning device the spinning rotor can be replaced by a spinning rotor with a different diameter. Furthermore, the opener device is capable of being displaced in relation to the spinning rotor. The rotor cover can be adapted through replacement on the one hand to replacing the spinning rotor, and on the other hand to the then applicable position of the opener device.
Claims13
An open-end spinning device, comprising:
- a replaceable spinning rotor of a given diameter provided with an inside wall, a fiber collection groove, and an open side;
- an opener device for supplying fibers to said spinning rotor;
- a machine frame having at least a first guide defined therein, said opener device further comprising members engaging with said guide so as to be variably positionable within a range defined by said guide in a plane relative to said spinning rotor;
- a replaceable rotor cover configured for said given diameter of said spinning rotor and disposed so as to cover said open side of said spinning rotor;
- a fiber feeding channel beginning in said opener device and ending in said rotor cover across from said inside wall of said spinning rotor so as to deposit fibers conveyed from said opener device to said inside wall, at least a portion of said fiber feeding channel being defined through said rotor cover and having dimensions and orientation dependent at least in part upon said given diameter of said spinning rotor;
- and
- wherein said opener device is displaceably mounted in at least one direction relative to said spinning rotor to accommodate different dimensions and orientation of said fiber feeding channel as a result of replacing said spinning rotor and said rotor cover with different sized spinning rotors and rotor covers.

An open-end spinning device, comprising:
- a replaceable spinning rotor of a given diameter provided with an inside wall, a fiber collection groove, and an open side;
- an opener device for supplying fibers to said spinning rotor;
- a machine frame, said machine frame comprising at least two shafts upon which said opener device is displaceably mounted, said opener device being variably positionable along said shafts between a plurality of operating positions relative said spinning rotor, at least one of said shafts further comprising notches defined therein corresponding to different sized spinning rotors, said opener device comprising a catch mechanism for releasably engaging said slots;
- a replaceable rotor cover configured for said given diameter of said spinning rotor and disposed so as to cover said open side of said spinning rotor;
- a fiber feeding channel beginning in said opener device and ending in said rotor cover across from said inside wall of said spinning rotor so as to deposit fibers conveyed from said opener device to said inside wall, at least a portion of said fiber feeding channel being defined through said rotor cover and having dimensions and orientation dependent at least in part upon said given diameter of said spinning rotor;
- and
- wherein said opener device is longitudinally displaceably mounted relative to said spinning rotor to accommodate different dimensions and orientation of said fiber feeding channel as a result of replacing said spinning rotor and said rotor cover with different sized spinning rotors and rotor covers.
