Definitions
- the invention relates to a press finger for one Flyer wing for guiding a fuse to one Coil surface.
- the roving on the flyer is known to be done by a Flyer wing with integrated sliver guide tube and by rotating the wing with a real one Provide rotation for consolidation.
- the roving is opened at the exit of the sliver guide tube passed the press finger and led to the press finger sheet.
- the press finger is usually designed so that a contact pressure is generated to a high spool weight to reach.
- the press finger blade with a guide groove and a round feed-through for the roving.
- the guide groove described here is a in Thread running direction tapered, V-shaped groove, the lateral boundaries are tangents that are in the open into a circular opening.
- This design is intended to shape the fuse Braking of the thread course and painting of protruding ones Serve fibers on the spool.
- the disadvantage here is that the Fused by getting a twist and the weird one Course of the guide groove wall from the guide groove strives out and not while laying down on the spool inevitably remains in the groove. This has negative ones Effects on the formation of the fuse when laying down the bobbin causes a decrease in thread quality and leads to more frequent ruptures.
- the object of the invention is therefore that Optimizing the sliver barrel so that an optimal shaping of the Fuse and binding of edge fibers before the Filing takes place on the coil and minimizing the Hairiness is achieved.
- the pear-shaped opening in the press finger sheet is one Transverse opening, from two sides through a curvature is limited, with one being a larger one Curvature diameter and the other a smaller one Has curvature diameter.
- This is above and below Opening delimited by two divergent straight lines, each merge tangentially into the arcs. The smaller the both diameters point in the direction of the match.
- the center of this opening is preferably in one Distance either above or below the center line and in the longitudinal direction in about the first third of the Press finger blade be arranged in the direction of the roving.
- the match guide groove is preferably exactly in the middle of the Press finger blade introduced. This starts with one Depth that is approximately half the thickness of the press finger corresponds, from the opening and ending, in The direction of the roving steadily becomes flatter, shortly before the Press finger edge. The flanks of this fuse guide groove only converge slightly in the direction of the match, so that they don’t touch until they run out.
- the tapering in the direction of the match The opening is slightly off-center, opens out in this case the upper flank tangentially into the larger one Curvature and the opposite flank in the area the smaller curvature.
- the fuse slides additionally supported by the tapering of the opening in Match direction and the arrangement described at the beginning the groove flanks to the opening, on the upper larger one Curvature and the adjoining groove flank. Thereby, and that the upper flank of the groove is only slight The fuse is forced into the groove and pressed against the upper flank.
- This optimal Match run causes an optimal shaping of the match and at the same time incorporating the edge fibers before Put it on the spool.
- the hairiness of the fuse is significantly minimized and thus leads to the securing of a high Final yarn quality and the manufacture flawless Drainage conditions of the roving in the following Spinning passage.
- the sliver guide groove is an accumulation of fibers and an This transition is to prevent the fuse from roughening a slope that goes from the bottom edge of the opening to the opening and deepest part of the match groove leads. It is also possible to change the slope to the bottom of the match groove with an additional Radius. However, the transition can be done exactly as Transition radius to be formed.
- the variant with the The groove guide groove in the middle should be preferred.
- the pressure finger sheet lies with pressure the coil.
- the fuse in the fuse guide groove the areas above and below this Use the task to thread the wound thread on the spool smooth out.
- the figure shows the design of a Press fingers for a right-handed fuse.
- the press finger of a flyer wing is known to exist from a press finger arm 10, which is only hinted at here is shown, and a press finger sheet 1.
- Das Press finger sheet 1 has an approximately rectangular shape, wherein however on the side on which the press finger arm 10 is attached, from the press finger arm 10 each Is worked obliquely.
- the thickness of one Press finger sheet 1 is about 3-5 mm.
- This opening 2 is of two Pages limited by a curvature 4, 14, the one a larger radius of curvature and the other has a smaller radius of curvature. Above and below is this opening 2 of two diverging straight lines limited, the tangential into the curvatures 4, 14th pass over. The smaller of the two curvatures 4 points in Match direction. The center of this opening 2 is at a distance slightly below the center line 15 and in Longitudinal direction about a third of the length of the Press finger sheet 1 arranged from the feed direction.
- a sliver guide groove is worked into this opening 2 3.
- This groove 3 extends in the middle of the Pressing finger blade 1 in the longitudinal direction, directly on the Opening 2 begins until a few mm before that Pressfinger blade end 6.
- the upper groove flank 5 lies tangent to the large radius of curvature and the lower one Groove edge 12 opens in the area of the smaller radius of curvature on.
- the flanks 5, 12 of the sliver guide groove 3 run from the opening 2 at the same angle in Match direction towards each other. This angle is however chosen so small that the flanks 5, 12 up to do not touch their leakage and a distance from each other.
- the depth t of the sliver guide groove 3 is at its lowest point, namely at the confluence with the opening 2 about half the thickness of the press finger sheet thickness. you The course in the direction of the roving is steadily flattening, so that they shortly before the press leaf edge 6 in the Pressfinger leaf upper edge 11 passes, the outlet is formed by a radius.
- the transition from the lower edge 13 of the press finger Opening 2 in the sliver guide groove 3 is a slope 7. Through this bevel 7 is a while the thread is running Prevention of fibers.
- the slope 7 is like this chosen that the fuse should wear through the opening 2 can slide into the sliver guide groove 3.
- the fuse is turned by rotating the flyer wing turned to the right and is due to the preserved Dralls strives to hike up.
- the oblique design of the transition 7 and the tangential to the large curvature 14 at a small angle the upper groove flank 5 lies the fuse of the winding process on the groove flank 5.
- the concern the fuse on this flank already supports before Winding up an optimal shaping of the fuse, edge fibers are integrated into the fuse and the hairiness of the Fuse is reduced significantly.
