Abstract

The invention relates to a winding strip (B) for a roller (W), serving to achieve an improved drawing value, on for example, a roller for a textile machine, a paper machine, a film machine a drive roller in transport units or similar. Said strip comprises an outer layer (11) of high drawing compatibility, for example of high roughness, whereby the outer layer (11) is connected to an inner layer (12) with positional stability. According to the invention, a winding strip whereby the roller may be equipped with a secure fixing without the use of an adhesive as fixative, which must be laboriously removed from the roller on renewing the winding strip may be achieved, whereby the inner layer (12), or the joint (v) between the inner layer (12) and the outer layer (11) comprises a high stiffness, in particular perpendicular to the longitudinal extent (arrow y) of the winding strip (B), which does not permit corrugations on the roller (W) under normal loads.

Description

00001 wrapping tape for a roller 00002

The invention relates to a to achieve a

00004 better take-away value serving wrapping tape for one

00005 roller such as a roller of a textile machine

00006 ne, a paper machine, a film machine, a

00007 drive roller in transport systems or the like, with

00008 an outside location of high portability, the

00009 outer layer arrested with an inner layer to secure the position

Is 00010. 00011

00012 Although, as expressed above, the

00013 invention relates to achieving a better

00014 generally relates to the value of rollers, is for simple

00015 ren representation below, however, on the operational

00016 offers in weaving machines, with a roller such as

00017 a train tree, a breast tree, a goods tree or

The like is addressed, reference. 00019

00020 The willingness to take along can be done in different ways

00021 be reached. For example, through a high roughness

00022 speed, but also by the choice of material, for example

00023 a soft plastic or a rubber or one

00024 rubber-like plastic, which materials have a high

00025 Ensure traction. In this respect, the outer location can also be a

00026 have a smooth surface. 00027

A common way of fixing the winding tape as

00029 Roll cover is made using adhesive as an adhesive

00030 intermediary to the roller. The practically periodically

00031 reallocation requires time consuming

00032 works, in particular with regard to the removal of

00033 residues of adhesive. In this regard, it is special

00034 care must be taken. Remaining particles can

00035 adversely affect the quality of the woven material. 00036 The roller also usually has to be completely removed. The

00037 time is also significant in this regard, which -

00038 not only in the field of weaving - according to a long time

00039 downtime is economically disadvantageous. 00040

00041 The object of the invention is to create a winding tape

00042 fen, which is a stable equipment of the roller without

00043 the application of when the winding tape is renewed

00044 laboriously removed adhesive from the roller as adhesive

00045 intermediary renders. 00046

00047 This task is first and foremost at

00048 a winding tape with the features of claim 1

00049 solved, it being based on the fact that the inner layer

00050 or in any case the bond between the inner layer and

00051 of the outer layer a high, in particular transverse to the longitudinal

00052 extension of the winding tape, at

00053 usual loads on the roller swellings not

00054 allows stiffness. Even at high that

00055 Goods that are easy to carry with you

In spite of the fact that glue has now been left out, it comes out as

00057 adhesion promoter does not cause swellings. Accordingly

00058 slip between the casing and the casing wall of the

00059 roller excluded. Responsible for this is

00060 seeing the stiffness of the inner layer or - by itself

00061 if necessary already fully sufficient or supplementary -

In any case, the bond between the inner layer and the

00063 outside location. The laminate-like structure works

00064 rend. This replaces the use of the usual ones

00065 lattice structure-like textile inserts as a means of

00066 reinforcement. A solution of even independent importance

00067 tung is then embodied in that the inner layer

00068 a ferromagnetic or ferromagnetic metal

00069 would be. With the metal layer it can in particular

00070 also in a plastic matrix, as a binder, 00071 contained barium ferrite powder or other ferromagnetic

00072 see or ferromagnetizable metal particles such as

00073 also hard ferrite. The inner layer can with the

00074 outer layer also connected, for example co-extruded,

00075 represents. In this embodiment, this occurs

00076 means of stiffness as protection against swelling

00077 still on that of an active suit against the roller.

00078 The assignment is easier because the documents are in

00079 immediately self-fixing way (expansion of the

00080 roller is unnecessary). Nevertheless, repositioning

00081 gene, for example for reasons of position correction,

00082 th. Magnetically responsive rollers are

00083 cases exist. It is also proposed

00084 that the inner layer is a metal foil. Such

00085 inner layer has a thickness of 0.2 mm to 1 mm before

00086 pulls 0.4 mm. Then there is an advantageous one

00087 feature that the inner layer is plastic-based

Is 00088. The corresponding material pairing can be

00089 in the sense of increased resistance to swellings

Be designed 00090. For example, it is recommended that

00091 the inner layer on the underside and / or on the top

00092 is sheer. A leathery, lobed structure is sought

00093 tur. 00094

00095 Insofar as, as further stated above, a magnetic

00096 do not see or magnetizable effect of the metal layer

00097 arrives, it can also be an aluminum

Act 00098 nium layer and / or a lead layer. 00099

Then the invention relates to the use of a in

00101 their width adapted to the circumference of a roller

00102 magnetic foil for helical or slit sleeve-like U sleeve

00103 development of the roller as a base for a winding tape for

00104 a roller such as tension boom, breast boom, goods

00105 trees in a weaving machine, preferably a winding tape 00106 according to one or more of the preceding claims

00107 1 to 6. 00108

The invention further relates to a roller such as an input

00110 addressed, for example a roller for goods transfer

00111 port in a weaving machine such as Zugbaum,

00112 breast tree, goods tree, which roller for better

00113 me of the goods with a winding tape wrapped helically

00114, which winding tape is an outer layer, for example

00115 structured and of high roughness, at least with

00116 very easy to take along, and one with this

00117 ge connected inner layer, which roller thereby

00118 is marked that the inner layer or in any case

00119 the bond between the inner layer and the outer layer

00120 such a high rigidity transverse to the longitudinal direction of the

00121 wrapping tape has that through the goods transport

00122 evoked, on the edge of the winding tape

00123 going forces not to warp the winding tape

00124 lead transversely to its longitudinal extent. On such

00125 Rolling is not just the rigidity compared to

Given 00126 lungs; rather, in the direction of rotation

00127 roller effective forces in the quasi a locking helix

00128 creating edge edges of the winding tape,

00129 supporting and supported edges. The free marginal

00130 edge of the laid turn acts as a "guideline"

00131 and guide stop for those who lay down next to each other

00132 turn section of the subsequent turn. Then it is proposed

00133 hen that the outer layer extruded the inner layer

00134 is. This represents a particularly economical production

00135 paired with the advantage of high precision. at

00136 of such a roll casing can then be considered

00137 be that the inner layer is a ferromagnetic

00138 or ferromagnetic metal layer, especially one

00139 metal foil. It is also provided that the

00140 inner layer is a metal foil that the inner layer is a 00141 has a thickness of 0.2 mm to 1 mm, preferably 0.4 mm,

00142 that the inner layer is plastic-based, that the

00143 inner layer underside and / or topside

00144 is schiert. 00145

00146 The invention also relates to a roller, which thereby

00147 is characterized in that the inner layer of an outer

00148 would be manufactured separately and only in the course of

00149 wrapping the roller a glue between the inner layer

00150 and outside location. That can be embodied in

00151 that the inner layer surrounds the roller like a slit sleeve.

00152 With this combined configuration, it can also be so

00153 that the inner layer turns the roller

00154 surrounds. Finally, it is suggested that

00155 between as a foil, in particular as a metal foil

00156 trained inner layer and the outer layer another

00157 metal foil is stored. Finally it is suggested

00158 gen that the inner layer with the intermediate layer is not

00159 is permanently arrested. 00160

The object of the invention is based on the following

The rollers W 00207 lying after a fabric edge 4 are breast beam 5, tension beam 6, an intermediate 00208 deflection roller and finally a goods beam 7. 00209 00210 Beyond the weft entry 8 are the so-called

00211 match tree 9 and the warp beam 10. 00212

00213 The chain runs from chain tree 10 on

00214 the match tree 9, the crosshairs and the shafts as well

00215 via train tree 6 to goods tree 7. The drive of the

00216 Zugbaumes 6 can from the usual drive

00217 Movement of the shanks can be derived, for example

00218 also via pneumatic winder. 00219

00220 The direction of transport of the warp threads 1 and

00221 of goods 2 is indicated by arrow x (see Figure 1,

00222 right). 00223

00224 The roll cover on the

00225 Zugbaum 6 constituting roller W. is roller-related

00226 a winding tape B. It is in principle multilayered, before

00227 trains two layers. For example, a location

00228 se facing the goods 2. It is an external

00229 would be 11 very easy to take along. Your leading to it

00230 structure is clearly shown in FIG.

00231 before. The high willingness to take along is

00232 example by a roughness-providing

00233 fracture reached, which fracture into the

00234 middle of thickness of the outer layer 11 is sufficient. The burr-forming

00235 Fissuring has a driving effect on the warp threads

00236 the 1 or the goods 2. 00237

00238 The other layer is an inner layer 12. Inside means

00239 facing the wall 13 of the roller W. The inner layer

00240 12 is much thinner than the thicker one

00241 Wear-exposed outer layer 11 of the winding tape B. 00242

00243 outer layer 11 and inner layer 12 are

00244 arrested. 00245 With regard to the desired winding ability of the

00246 bonded layers has a lobed structure.

00247 There is a laminate-like structure of high strength

00248 in itself and primarily also in the area of the

00249 of the V of both layers 11, 12, i.e. the

00250 interfaces between outer layer 11 and inner layer 12. 00251

00252 This is primarily to achieve a better take-away value

00253 tes serving wrapping tape B is designed to

00254 that the inner layer 12 or in any case the said

00255 bundle V between the inner layer 12 and the outer layer 11

00256 a high arrow, in particular transverse to the longitudinal extent

00257 y of the winding tape B, in usual

00258 loads on the roller W do not allow swellings-

00259 en has rigidity. 00260

00261 The type of winding is like that from FIG. 3, for example

00262 emerges, helical. It turns after turn

00263. The depositing of the progressive turns

00264 looks on the bare surface of the jacket wall 13. 00265

00266 The ends of the winding tape B wedge at an angle

00267 Alpha, which is parallel to an end face

00268 leads the wrap. 00269

00270 The end turns of the associated winding tape

00271 B are by a ring-like insulating tape 15

00272 fixed. The attachment is tight. to

00273 application comes, for example, an adhesive tape. 00274

00275 For permanent assignment, the insulating tape 15 can, for example

00276 half with the outside of the winding tape B and

00277 in half with the end zone of the jacket wall 13 in composite

00278 stand. 00279 00280 Wrapping can be sufficient, not excessive

00281 tightness. 00282

00283 Because of the

00284 extension arrow y of the winding tape B given the

00285 ability to swell in the manner shown in FIG.

00286 provided gusset space 16. The corresponding tensile forces

00287 could otherwise be there if the transverse stability is insufficient

00288 Wrapping tape B to walk-like poses of this local

00289 tape section lead. Because of the particularly

00290 free connection of winding tape B and roller W are

00291 effectively prevents such swellings. The free

00292 edge of the laid turn acts when covering

00293 not only as a visually usable "guideline",

00294 but also as a guide stop for yourself

00295 adjacent winding section of the subsequent win

00296 fertilizer The free edge is designated 14 '; the

00297 touching edge in front of the subsequent winding

00298 bears the reference number 14 ''. 00299

00300 occur on the roll body thus wound in the radial direction

00301 de erasing forces are caused by the marginal edges 14 ',

00302 14 '' locked. The shifting forces are transformed into one

00303 implemented axial component. The longitudinal central axis of the

00304 roller W is denoted by z-z. 00305

00306 So there is clearly a roughened surface, which without

00307 With the help of glue in a firm bond

00308 to the wall 13 of the roller W is. 00309

00310 The pitch angle of the spiral-shaped joint

00311 14 is dependent on the width of the band and the

00312 roller diameter different. In a simple way

00313 this angle results from the following relationship:

00314 The diameter of the roller is multiplied by pi and 00315 then results in a certain length. For example, for 00316 with a diameter of 100 mm, a length of around 314 00317 mm. This length is then - in the form of a straight line - 00318 starting from a corner of a right-angled end 00319 end of a band, so that the end 00320 of this straight line lies against the opposite (second) 00321 longitudinal edge of the band. The included 00322 angle between the first longitudinal edge (from which 00323 the straight line extends) and the 00324 straight line is the angle of the helical 00325 joint. In practice, the procedure is also such that 00326 the triangular surface enclosed by the straight line, which can also be called hypotenuse 00327 of a right-angled triangle, is cut off and the 00329 exposed hypotenuse then serves as the contact edge, so 00330 that the given angle when wrapping then from 00331 itself. 00332 00333 The inner layer 12 is also a ferromagnetic or 00334 ferromagnetic metal layer. The roller W or at least one cladding layer of the cladding wall 13 00336 is magnetically responsive. This results in a polarity-correct 00337 assignment of the winding tape B. Last effect 00338 also contributes to the slip-free assignment of the winding tape B. A corresponding 00340 hard core of the inner layer 12 further improves the rigidity which does not allow the swellings 00341. 00342 00343 It is then advantageous if the inner layer 12 is a 00344 metal foil. Such an inner layer has in Wickel00345 tapes B of the order of magnitude described above a 00346 thickness of 0.2 mm to 1 mm, preferably 0.4 mm. The 00347 metal foil is shown in FIG. 4 and has 17 be00348. It is preferably plastic-based. 00349 00350 In achieving an embedding of the metal foil 17

00351 on the top and bottom of the same a plastic

00352 layer, the outer layer 11 facing 18 and the

00353 facing 13 designated 19. The addressed

00354 Chen plastic lamination results in the drawing

00355 from FIGS. 4 and 6. It gives the inner layer 12

00356 an additional stiffening effect. 00357

00358 Figure 6 shows a variant insofar as there

00359 the metal foil 17 does not consist of a coherent

00360 layer consists of a scatter layer. The

00361 Reference signs are used analogously for understanding. 00362

00363 which embed the metal foil 17 or the like

00364 Plastic layers 18, 19 consist of PE. The above

00365 the outer layer 11 adjoining the boundary V

00366 is made from TPE. 00367

00368 The layer connection is done by congruent opening -

00369 transfer the outer layer 11 to the inner layer 12. 00370

00371 The variant shown in FIG. 7 sees the use

00372 fertilizing a winding tape B ¹ before. This wrapping tape B '

00373 contains the hard soul already indicated above. It leaves

00374 also without the use of adhesive of the roller W im

00375 Assign ways of helical winding. Secured

00376 this roll cover is also by the end

00377 applied insulating tapes 15. 00378

00379 The hard soul is set so that on the one hand the

00380 winding ability is given, but on the other hand

00381 emergence is prevented. 00382

00383 The variant according to FIG. 8 provides a roll cover

00384 such that between the formed as a metal foil 00385 the inner layer 12 and the outer layer 11 a so

00386 connected at least transverse stable inner layer, for example

00387 a correspondingly thick and / or stiff metal film

00388 lie 20, is stored. This specification is suitable

00389 itself does not respond magnetically to rollers W

00390 material such as aluminum. The

00391 Wrapping is done in opposite directions. 00392

00393 Here is the inner layer 12 with the intermediate layer

00394 not arrested. Nevertheless, the

00395 quickly unwind outer layer 11 from roller W and through

00396 Equip new occupancy effectively. The reference numbers of the

00397 basic version are also entered here without text

00398 repetitions. 00399

00400 As far as the variant Figures 9 to 11, so

00401 surrounds the jacket wall 13 of the roller W a slotted sleeve

00402-like inner layer 12. The slit sleeve 21 is as such

00403 designated 21. The slotted sleeve consists of tape

00404 material, but what according to Figure 9 like a cuff around

00405 the body of the roller W is placed. Accordingly stretches

00406 the slot joint 22 is parallel to the longitudinal center axis

00407 se z-z of the roller W. 00408

00409 The slotted sleeve 21 represents the base or the wide

00410 underlay and length of this roller cover

00411 train Here, too, it may be a magnetic

00412 lie. The described attachment can then end

00413 on captivating rings 15. The slot-

00414 sleeve 21 is then assigned a conventional winding tape B2

00415 net, which is an introduction with regard to the status of

00416 technology was described. This usual winding tape B2

00417 points to the outer surface of the slotted sleeve 21

00418 side a layer 24 of adhesive as adhesive 00419 middle on. Here is also the one described above

00420 spiral winding made. 00421

00422 The layer 24 does not come with the outer surface of the

00423 roller W in contact. For the new one to be carried out

00424 roller cover is simply along with a cutter

00425 the slot joint 22 as a guide trench and so

00426 the old covering is cut open and removed. The man

00427 cuff can be opened by gaping. 00428

00429 Figure 10 is a sub-variant of the slotted sleeve

00430 21. In this, the slot joint 22 is not open

00431 shortest axial path between the ends of the Schiitzhül-

00432 se executed, but in a spiral line. Here too

00433 the reference numerals are applied accordingly. The spiral

00434 shaped slot joint 22 goes on a hand

00435 wide axial section over at least one

00436 quarter circle of the sleeve body. Even in this technical

00437 see execution results in the one highlighted above

00438 advantage of running the slip load into the

00439 Axials of the roller W. The edge channels that face each other

00440 th are also designated here with 14 ', 14' '. 00441
