Definitions
- This invention is concerned with the garnishing of a card in a revolving flat card, in particular but not exclusively with further developments of the solutions set out in CH 2303/97 from 01.10.97 and in CH 2816/97 from 05.12.97.
- CH 2303/97 and 2816/97 are hereinafter referred to as the previous applications ".
- the invention according to the previous applications provides a garnished flat bar for use in a revolving flat card, the tips of the set in Groups are divided.
- the groups can each have a garnished surface with a length form larger than 1000 mm.
- At least two in the longitudinal direction of the flat bar can be arranged side by side extending clothing strips are attached to an elongated support.
- the strips can have different clothing parameters, e.g. Wire lengths, Wire thickness, cutlery density or setting patterns.
- Each group can have peaks that form in the card to form a respective one Level of equipment, e.g. with its own heel zone. Since the groups are preferably attached to a common support, the Arrangement sufficient strength to make precise adjustments to the lid tips compared to the drum set over the entire working width.
- the present invention is a.
- the present invention provides a method of making a flexible yarn door for a card cover, with a wire or tick set using a Grinding device is ground to set the wire height while maintaining an elongated Form cutlery.
- the grinder can be when grinding the Move the clothing in the longitudinal direction of the cutlery surfaces.
- the method according to the invention is intended in particular for use in a case where the set has multiple wire groups.
- the groups can through the Loops are formed, at least one group having a cut that differs from the cut of another group.
- the method can e.g. are used to grind the wires of only one group and thereby for this Group to form a cutlery area that is opposite the cutlery area or the cutlery of the other group (s) is on a different level.
- a similar arrangement can also be achieved if more than one group is (simultaneously) ground.
- FIG. 1 schematically shows a revolving flat card 1 known per se, for example card C50 from the applicant.
- the fiber material is fed into the filling shaft 2 in the form of dissolved and cleaned flakes, taken over by a breeze or licker-in 3 as a wadding, passed over to a drum or drum 4 and dissolved and cleaned by a traveling cover set. Fibers from the nonwoven fabric located on the reel 4 are then removed by a pickup 7 and formed into a card sliver 9 in an outlet section 8 consisting of different rollers.
- This card sliver 9 is then deposited from a sliver holder 10 into a transport can 11.
- the card is with one 1, but is well known to the person skilled in the art.
- the revolving cover set comprises revolving cover rods 13 1, but not explained in detail below, each rod 13 is provided with a set which cooperates with a set (not shown) on the drum 4.
- the covers 13 are fastened to a chain or a belt 5 (for example according to EP-A-753 610) and they are thereby closed Cover path "(via deflection rollers 6) moved in the opposite direction or in the same direction to the direction of rotation of the drum 4, with one Vorlauf "(from an entry point E to an exit point A) the carding work and on the Return "the lids are cleaned at a cleaning point 60.
- the cleaning device is explained in more detail in EP-A-800 895.
- the lids 13 can be ground at point 62 according to the same application.
- the essential elements of the revolving lid assembly are therefore the individual ones Mobile lid 13, each flat bar comprising a support section and a clothing strip.
- the support section must have the necessary strength and rigidity to enable precise working gaps between the cover sets and the drum set, both in the middle of the working width and on the card plates Construction of the carrier section is shown in Figures 8 through 11 of US-B-5,542,154, but many suitable alternatives are known, and of course the carrier section must also have surfaces to which a clothing strip can be attached.
- Fig. 2 only serves to explain the term Heel ". It shows schematically a part of the drum 4 with its sawtooth set 15, which has a lateral surface 16. In addition, two conventional flat clothing strips 17 and 18 are shown. The carrier parts of the flat bars which carry these strips are not shown in FIG. 2 , since they are irrelevant for the explanations that follow. These carrier sections are formed and guided in the card in such a way that they are the Geometry "of the opposing clothing tips enable what is well known to the expert.
- the trim strip 17 or 18 of a lid can comprise a flexible (semi-rigid) or an all-steel trim (see the manual for this) A Practical Guide to Opening and Carding "by W. Klein, page 49, publisher: The Textile Institute).
- the preferred flexible sets have tips that pass through Wires "D are formed, the wires in one Basis "B (also Foundation "called) are inserted to form a strip that can be attached to the support section.
- the wires D are with a Knee "as shown in the manual and (schematically) in FIG. 2, the knee being omitted in the further schematic figures for the sake of simplicity, since it does not play a role in the present invention.
- FIG. 2 is greatly simplified. However, it contains the essential elements for explaining the Heel".
- the base B has a certain width, which depends on the width of the support section, and is a narrow width within this base width Set width "SB equipped with wires.
- the base width is approx. 35 mm, the set width approx. 22 mm.
- the wires themselves are standardized (DIN / ISO 4105, edition 1984).
- Each wire is usually in its free end with both Side grinding "as well as with a Due to the side grinding (which can be seen from EP-A-800 895), the end section is intended to taper towards the free end, while the relief creates a point at the free wire end.
- the direction of rotation of the drum 4 is indicated in Fig. 2 with an arrow.
- the direction of movement of the clothing strips is not shown because it is insignificant in this context - irrespective of whether the clothing strips 17, 18 move in the same direction as the clothing tips of the drum (in the same direction) or in opposite directions, results from the much higher speed of the Drum set for each strip 17.18 one Front "VS and a rear side HS of the strip.
- the wire tip is formed on the front of each wire.
- FIG. 3 shows schematically the set of a single flat bar (which is itself not shown) with a set width SB of the entire set strip.
- the tips of this strip are divided into two groups (a front group VG and a rear group HG), the names front "and rear "correspond to the explanations of FIG. 2.
- the arrangement according to FIG. 4 differs from the arrangement according to FIG. 3 only in that the tips in each heel zone have a Heel cut ".
- HG there is a respective set of cutlery E1 and E2 for the front tip group (similar to FIG. 3) and a respective heel level F1 and F2, which are angled from the cutlery levels of the front tip groups 4 can basically consist of an arrangement according to FIG can be obtained by grinding the tips in each heel zone in addition to the angled ones To form planes "F1, F2.
- Fig. 4 also shows a preferred variant of the heel cut, according to which the tips of the heel zone are actually not in one Plane ", but lie in an imaginary surface F1, F2 with a curvature that is concentric with surface 16.
- Gaps "between groups VG and HG of Figures 3 and 4 are provided, although such gaps are known from the prior art.
- Gaps "can be used ie there can be a distance (not shown) between the front and the rear group. This gap is unlikely to bring about an improvement in the carding effect, on the other hand it is also unlikely to lead to any deterioration because the tips of the rear group HG, which are close to the heel of the front group VG, can hardly achieve any great effect, and a gap (or a distance) can be used (and arranged accordingly) to prevent the formation of Fleece bridges "as explained in CH 2816/97.
- Fig. 5 now shows constructive measures that can be used to 3 and 4 to implement the garnishing concepts in practice. For the sake of simplicity was only shown in this figure sets without heel cut - from which already said it will be clear, however, that the flat bar designs shown for Sets with or without heel cut can be used.
- Execution 5 comprises a conventional base B (uniform thickness).
- the groups VG and HG consist of wires D1 and D2 of different lengths, the wires D1 in the front group are slightly longer than those D2 in the rear group. For one Given the wire thickness, the wires D1 of the front group are therefore more elastic than those in the back group, which is not always desirable.
- FIG. 6 An approach for a solution to this problem is shown in Figure 6 - it is the wire gauge of the front group compared to the wire thickness of the rear group.
- this solution is in combination with a conventional flat bar (with a garnish strip according to FIG. 2), but it could be in a garnish strip 5 are used.
- the present invention deals with the question of how a lid set according to Fig. 5 (at most in combination with FIG. 6) can be produced inexpensively. From that it is assumed that the process for producing a cover set is conventional today, as is to be explained initially with reference to FIGS. 7 and 8.
- Fig. 7 shows a belt R made of a composite material which is suitable for the base (or foundation) of a clothing strip.
- the width of the belt R (in figure 7 not visible) corresponds to the length of the strip or the flat bar.
- the strap R is equipped with wires (or ticks) D (i.e. the wires are in the material of the belt), these wires are arranged in sets so that the Sets Z1, Z2, Z3 etc. by cutting the belt R between the sets one each Can form a cover set (a set strip).
- the sentences Z1, Z2 etc. each have two wire groups with an intermediate distance A. From Figures 3,4 and 5, however, it can be seen that the distance A is not essential to the invention.
- the wires D must be ground, so that the wires of a set each have a predetermined height (opposite the base) exhibit.
- all wires D of a set are supposed to have the same height, e.g. can be achieved by means of a device according to FIG can.
- the belt R which normally has a width of approx. 1000 mm.
- the roller W2 having a diameter of approx.2.5 m. having.
- the block to be ground is placed by the large roller W2 against the contact pressure the grinding roller SW supports, while the height of the wires D by itself rotating grinding roller is set.
- the grinding is therefore carried out in the longitudinal direction versus rhyming R. It will then be in a further step (not shown) carried out the aforementioned side or relief grinding, after which (in conventional procedure) it is then only necessary to add the clothing strips (BasIs + cut wires) by cutting the belt, after which the strips can be attached to their respective supports (flat bars).
- FIG. 8 A rotating grinding wheel Sc is on a carriage (not shown) mounted) and is thus movable in the transverse direction (opposite the belt R) what corresponds to the longitudinal direction of the wire set or the strip.
- the disc points such a width that it brought into contact with the wires of only one group can be. Because the disc Sc spreads the wires to only one group these wires then have a different height (a different cut), than the wires of the other group.
- the belt including the wire set to be ground
- the belt be supported by a counterhold G against the contact pressure of the disc.
- the two groups can then be given the side grinding or relief grinding be what by means of the appropriate conventional processing steps can be carried out.
- Fig. 9 shows one stepped grinding wheel St, which has two wheel diameters.
- the two disc levels can be used to process one wire group at a time to generate one wire height each.
- Fig. 9 this is schematic with the wire heights h1, h2 indicated (h1> h2).
- a conventional grinding roller falls SW (Fig. 8) away - all wires are processed in the longitudinal direction of the strip.
- FIG. 10 There is, however, another possibility of changing the conventional method to form the new clothing strip, as will now be described with reference to FIG. 10.
- a strip consisting of a base and a not yet ground wire set
- the attachment can be done using conventional clips (not shown).
- the wires are divided into two groups, which are separated from one another by the aforementioned distance A. After grinding, these groups should each have one Form card edge ".
- the carrier section TP can now be held in a suitable holder while a grinding wheel Sc (see FIG. 8) first in the longitudinal direction of the strip one and then the other wire group processed to the respective wire heights to form h1 and h2. It can then be used for each group of side grinding and Relief grinding.
- a grinding wheel Sc see FIG. 8
- both wire heights could at the same time, by means of a stepped disc (cf. FIG. 9), which at best would be advantageous because then the parts would not be relative to each other between grinding operations have to be moved.
- FIG. 11 again shows the elements of FIG. 10 with additions to explain various aspects of the Geometry "of the overall arrangement.
- the imaginary outer surface of the card drum assembly is indicated by M.
- the underside of the carrier section TP opposite the card drum can be regarded as reference plane E0.
- the two wire groups each have a placement level E1 or E2
- the planes E1, E2 can enclose an angle ⁇ , whereby this angle can also be zero, ie the planes E1 and E2 can be arranged parallel to one another.
- the plane E1 or E2 can also form an angle with the reference plane E0 (not shown). include or run parallel to it.
- the distance A can be set to zero.
