Abstract
A roving frame has operating elements which engage rods mounted on a shank of each flyer of a flyer rail transversely to the pivot axis of the rod which is offset from the rod. The pressing fingers are swingable about this axis and can be urged outwardly to clear the bobbins and thus allow bobbin replacement.
Claims23
A roving frame comprising:
- a support;
- at least one row of spindles on said support for receiving respective bobbins for spinning respective rovings at respective work stations;
- a respective flyer at each of said stations cooperating with the spindle and having:
- a flyer body at an end of the flyer and rotatable about a rotation axis aligned with the respective bobbin, and
- a pair of shanks attached to the respective flyer body and extending downwardly from the respective flyer body straddling the respective bobbin;
- a respective pressing finger pivotally mounted on one of said shanks of each flyer swingable about a pivot axis inwardly toward and outwardly away from the respective bobbin into an inwardly swung position and an outwardly swung position for pressing turns of spun roving thereagainst in said inwardly swung position of the finger;
- a pressing finger rod secured to and carrying said pressing finger at a lower end of said rod and being offset from said pivot axis, said rod extending from said pressing finger upwardly along said one of said shanks to an upper end of said rod;
- and
- a device cooperating with the pressing finger rods of said flyers and including a respective operating element engaging each rod transversely to the respective rod for retaining each pressing finger of a respective flyer in the respective outwardly swung position of the respective finger.
