Abstract
Open end friction spinning apparatus is provided in which there are one or more spinning units with respectively two adjacently arranged rollers, rotating in the same direction, and disposed to form a wedge shaped gap therebetween for accepting fibers and spinning them into a thread of yarn. A housing is provided for each spinning unit, which housing includes a stationary housing part carrying bearing devices for the rollers and a hingedly mounted cover type housing part connected at a pivot axle. The cover type housing part carries at least a part of a feeding channel for feeding fibers to the rollers to be spun.
Claims35
Open end friction spinning machine having machine frame means and at least one spinning unit, each spinning unit comprising:
- a pair of friction rollers disposed adjacent one another to form a wedge shaped yarn forming gap therebetween;
- fiber supply means for supplying fibers to the wedge shaped gap, said fiber supply means including fiber feed channel means opening adjacent the wedge-shaped gap;
- yarn withdrawing means for withdrawing formed yarn from the wedge shaped gap;
- and
- housing means surrounding at least a portion of the friction rollers defining the wedge shaped gap,
- wherein said housing means includes two housing parts separated from one another in a region of a plane extending substantially parallel to the rotational axes of the friction rollers, a first of said housing parts being disposed at the side of the friction rollers opposite the wedge shaped gap and being arranged at the machine frame means, the second of said housing parts being disposed at the wedge shaped gap side of the friction rollers and being mounted for selective movement between a closed housing position for spinning operations and an open housing position with said wedge shaped gap being accessible from outside, said second housing part further carrying a portion of the fiber feed channel means which opens adjacent to the wedge shaped gap.
Open end friction spinning machine having machine frame means and at least one spinning unit, each spinning unit comprising:
- a pair of friction rollers disposed adjacent one another to form a wedge shaped yarn forming gap therebetween;
- bearing means for rotatably supporting the friction rollers,
- fiber supply means for supplying fibers to the wedge shaped gap, said fiber supply means including fiber feed channel means opening adjacent the wedge-shaped gap;
- yarn withdrawing means for withdrawing formed yarn from the wedge shaped gap;
- and
- housing means surrounding at least a portion of the friction rollers defining the wedge shaped gap,
- wherein said housing means includes two housing parts, a first of said housing parts being disposed at the side of the friction rollers opposite the wedge shaped gap and being arranged at the machine frame means, the second of said housing parts being disposed at the wedge shaped gap side of the friction rollers and being mounted for selective movement between a closed housing position for spinning operations and an open housing position with said wedge shaped gap being accessible from outside, said second housing part further carrying a portion of the fiber feed channel means which opens adjacent to wedge shaped gap, said first housing part extending axially along the length of the friction rollers to form a bearing body support receptacle means for accommodating the bearing means for the roller shafts.
