Definitions
- the invention relates to a scissor coil with a blade part for a rotating Shear cylinder, which works with a counter knife to shear fiber pile, the blade part consisting essentially of an upright spiral Band exists, the outer narrow side of which has a cutting edge and where a breast surface adjoins the cutting edge, which with the counter knife has cutting, interacting blows.
- Shear spirals of this type are described in DE-AS 24 04 837.
- the two wedge surfaces on the cutting edge of the shear helix each including a cutting angle with the helix axis.
- the aim is to prevent the fibers from dodging sideways during shear cutting - as is the case with scissors with a serrated cutting edge.
- the cut of the known scissor helix is essentially designed so that each cut edge of a wedge-shaped cut interacts approximately like a punch with the counter knife. In this way, a uniform fiber pile can only be produced if the amount of fibers fed to the respective wedge or slicing cutting edge is kept relatively small.
- the transport speeds of the fibrous webs to be sheared, particularly in the case of dense pile, are correspondingly limited. If the transport speed or the (relative) cutting depth is increased above a limit to be determined in the individual case, part of the pile covered between the counter knife and the wedge cutting edge is pushed aside so that uneven shear results are obtained.
- the term Cutting depth denotes the (average) length of the pile part which is cut off with the individual cut. Relative "cutting depth is the ratio of the length cut to the original (mean) total length of the pile.
- the invention has for its object to design the cutting edge of the scissor helix so that the transport speed of the fabric to be sheared and / or the Cutting depth, even with dense pile, essential compared to the state of the art can be increased and still maintain an evenly sheared fiber pile becomes.
- the solution according to the invention exists for the shear helix mentioned at the beginning in that the blows are formed as arcuate recesses in the chest surface are.
- the depth of the blows should preferably be perpendicular to the chest surface on the order of magnitude at least equal to that measured parallel to the cutting edge Width of the blows.
- the invention at the same time makes it available for holding fibers standing volume of the individual cut is maximized and the cutting edge is cut open extended almost the entire length of the arcuate slash. Therefore one of the Pile density, cutting depth and the fabric web speed large amount of fibers can be caught in a single cut without the fibers dodge laterally parallel to the cutting edge of the counter knife or - as with a conventionally wedge-shaped described in said DE-AS 24 04 837 Slash - can be pushed into a chisel tip.
- the arcuate slash volume namely, according to the invention not only offers space for significantly more fibers than the known flat wedges, but it also has no wedge tips in the fibers could dodge. According to the manufacturing mechanics, the arch shape be constructed from a plurality of essentially flat elements.
- the blows according to the invention can approximately average Stretch into the chest surface in the shape of an arc, ellipse or parabola.
- the scope of the invention also includes any other arch shape that has a maximum receiving volume guaranteed for fibers and the longest possible cutting edge.
- an approximately parabolic cross section of the Slash recess, the parabolic axis of which is approximately perpendicular to the cutting edge of the Counter knife stands. If necessary, the parabolic cross sections open approximately symmetrically in the direction of the counter knife cutting edge.
- the cutting edge of the scissor coil should be designed in this way be that the transport speed of the web to be sheared and / or the cutting depth of the pile - even with dense pile - compared to the state of the Technology can be increased significantly and still a uniformly sheared Flor is obtained.
- the slashes are arcuate recesses the chest surface of the scissor coil.
- the depth of the Lashes perpendicular to the chest surface should be at least equal in size the width of the blows measured parallel to the cutting edge of the shear helix become.
- Fig. 3 part of a scissor coil 3 is enlarged with a cut 13 on the chest surface 14 shown.
- the shear coil 3 shown consists of the spiral band 15 with cutting edge 6 and foot 16.
- the chops 13 according to the invention of the chest surface 14 in strong enlargement in one perspective and shown in principle in cross section.
- the single cut 13 of the shear helix 3 is essentially in Cutting direction 17 moved perpendicular to the cutting edge 12 of the counter knife 7.
- the shear area shifts in the direction of propagation 18 parallel to Cutting edge 12.
- the angle ⁇ of the shear helix 3 relative to the cutting edge 12 becomes referred to as spiral pitch.
- the depth T of the cuts 13 in terms of magnitude at least equal to that parallel to the cutting edge 6 of the Schertoryl 3 measured width B of the cuts 13 are made. Moreover is aimed at the arcuate in cross section (cut perpendicular to the chest surface) Chop 13 to shape or to arrange relative to the counter knife cutting edge 12 or to orientate that as large a part of the cut length as possible interacting with the counter knife 7.
- the cutout has an approximately parabolic cross-section is selected, the parabola axis (containing the parabola focus) 20 should be approximately perpendicular to the cutting edge 12 of the counter knife 7. - In the Direction of the cutting edge 6 measured width of the webs 21 between two blows 13 is generally approximately zero.
