Definitions
- the invention relates to a spreader roller for smoothing a layer of fabric, which is designed as a round brush with a base body and bristles projecting beyond its outer lateral surface by means of a free end section, the bristles being combined as bristle bundles spaced apart from one another and these bristle bundles being fixed to the base body by means of a fastening section and wherein bristle bundles arranged on both sides of a transverse central plane of the base body run obliquely to the transverse plane of the base body, in that their free end sections are inclined in the direction of the ends of the base body, such that when the spreader roller interacts with the fabric layer, a transverse tension can be achieved on this.
- the invention relates to a device for smoothing a textile fabric in its area over which a spreader roller runs, wherein the spreader roller, which interacts with the surface of the fabric and is designed as a round brush, has a cylindrical base body with bristles attached thereto, which, combined to form bristle bundles, protrude beyond an outer lateral surface of the base body and whose bundles of bristles are each arranged at a distance from one another, with free end sections of the bristles that act on the fabric being able to longitudinally tension the fabric in a direction in which there is a relative movement between the fabric and the spreader roller and on the other hand by obliquely inclined toward the ends of the base body, arranged on both sides of a transverse median plane of the base bristle bundles of bristles in the interaction of the spreader roller with the fabric on this a transverse tension can be achieved.
- Rotating brushes which are used to smooth fabrics or foils, are generally known and can interact with them in a manner as can be seen from FIGS. 15 to 17, which show the principle of action in a simplified form.
- a layer of fabric 47 which can be formed, for example, as a web of textile material and is to be smoothed, is spread out on a base 48.
- a rotating round brush 49 shown in FIG. 15 consists of a base body 50 with bristles 51 arranged on its outer lateral surface and is, according to this illustration, such as illustrated by a directional arrow 52, counterclockwise driven. Furthermore, the round brush 49 pressed against the fabric layer 47 with a force acting orthogonally to the base 48 is moved in a displacement direction 53 relative to the fabric layer 47 .
- the direction of rotation of the round brush 49 (see direction arrow 52) is in the opposite direction to a rolling movement resulting from the direction of travel 53, as a result of which an area of the fabric layer 47 lying behind the round brush 49 in the direction of movement is pulled across its width, primarily in the longitudinal direction, so that creases in the Stoffla ge 47, which run transversely to the direction of travel 53 of the round brush 49 in the untreated layer of fabric, can be removed.
- Such interaction of the bristles 51 of the round brush 49 with the fabric layer 47 is also referred to as a function with trailing bristles 51 or as the "weather vane effect", in which the friction of the bristles 51 on the fabric layer 47 causes a tensile force in its longitudinal direction.
- the round brush 49 generates an essentially uniaxial tangential tension behind it in the direction of travel 53, i.e. in the area traveled over. Rather, it is often the case that these are only generated by the tangential tension of the round brush 49 and are otherwise reinforced by this by flattening, so that they can hardly be removed.
- a bristle bundle 55 is provided which, according to FIG. 17, is placed orthogonally on the surface of the fabric layer 47 and is pulled over it under slight pressure. It can be seen here that the soft bristles 51 of the corresponding bundle of bristles 55 give way as trailing bristles 51 counter to the direction of travel 53 .
- a spreader roller for smoothing a fabric layer of the type mentioned in the respective preamble of claims 1, 12 and 13 is known from DE 10 2004 038 165 B4.
- a spreader roller referred to as a spreader roller from a Wal zengrund Archives and arranged on this bundles of bristles, which are arranged inclined in particular in the two end regions of the roller body to the left and to the right in Rich direction of its ends.
- a web that is guided on the outer surface of the spreader roll and is, for example, a film web your can be smoothed on the one hand by the longitudinal forces generated by the bristles and on the other hand by means of the transverse forces generated by the obliquely running tufts of bristles.
- the roller body is freely rotatably accommodated in bearings of a holder.
- the spreader roller is provided for deflecting a running web and is thus driven by the moving film web.
- the spreader roller can also have a motor drive, by which the spreader roller is driven at such a speed that the resulting circumferential speed of the inclined bristle ends essentially corresponds to the running speed of the web guided under tension.
- This deflection of the film web without longitudinal creases or eliminating existing longitudinal creases presupposes that the web rolls off the spreader roller and that there is essentially no relative speed between the running speed of the film web and the circumferential speed of the spreader roller. It is therefore a matter of passive unrolling of the film web on the spreader roller. Under this condition that a relative speed is avoided, a smoothing of the film web can be achieved, so that it has neither longitudinal nor transverse creases.
- the object of the present invention is to create a spreader roller designed as a round brush with which, for smoothing a layer of fabric, tensions can be introduced into the layer of fabric both in the longitudinal direction and in the transverse direction, even at a relative speed occurring between the circumferential speed of the spreader roller and a travel speed of the layer of fabric are.
- a spreader roller for smoothing a layer of fabric is designed as a round brush with a base body having bristles protruding over its outer lateral surface.
- the bristles are grouped together as bristle bundles spaced apart from one another, with these bristle bundles having a fastening section fixed to the base body.
- each running on both sides of a transverse center plane of the base body arranged designated bundle of bristles obliquely to the transverse plane of the base body, by the free Endab sections are inclined towards the ends of the base body, such that when the spreader roller interacts with the fabric layer on this, a transverse tension can be achieved.
- each bristle bundle should be taken up by a recess formed in the base body in a second section, which adjoins the fastening supply section.
- the recess should essentially extend in the radial and axial direction of the base body, with the bristle bundle arranged in the recess being guided on both sides on first side walls that extend in the axial direction of the base body.
- the respective bundle of bristles running at an angle of inclination to the surface of the layer of material should be pivotable in the direction of the respective end of the base body by applying a force to the free bristle ends.
- the spreader roller according to the invention is suitable for an application in which a relative speed occurs between it and the surface of the fabric layer, i.e. a peripheral speed achieved by a drive of the spreader roller is higher than a peripheral speed caused by the relative movement of the spreader roller with respect to the surface of the fabric layer.
- This relative speed also increases when the spreader roller is used in the opposite direction to the direction of rotation that results from the movement in the direction of travel.
- the casserole effect of the obliquely running bundles of bristles is intensified by the fact that they can easily execute a pivoting movement in the plane running through the longitudinal axis of the spreader roller within the recesses due to the degree of freedom created thereby. Only this pivoting movement of the bristle bundles about their attachment section is possible because they are guided in the circumferential direction on the first side walls.
- This pivoting movement has the effect that the ends of the bristles which run up against the surface of the layer of material very effectively stretch the layer of material in its two directions running transversely to the direction of travel of the spreader roller.
- the Alignment of the recesses with their longitudinal extensions parallel to the longitudinal central axis of the spreader roller can also be modified in such a way that the longitudinal extensions of the recesses are aligned at an angle to the longitudinal central axis, i.e. run helically on the outer lateral surface of the base body.
- the trailing effect that occurs can be specified at the bristle ends.
- the bristle hardness effective at the end of the bristles in the two coordinate directions “axial direction” and “circumferential direction” of the spreader roller can be specifically influenced separately from each other. If the relative speed is increased, this can bring about a further intensification of the casserole effect between the corresponding bundles of bristles and the fabric layer.
- the recesses see ge in cross section, be formed like slots, the bundles of bristles being guided on both sides on first side walls which run parallel to one another and extend in the axial direction of the base body.
- the bundle of bristles is consequently supported in the circumferential direction by the side walls in the area between the fastening section and the outer lateral surface of the base body, so that there is less of it in the circumferential direction free bristle length results and thus a greater bristle hardness is achieved at the free bristle ends.
- the recesses viewed in cross section of the base body, are arranged in the base body in such a way that the bundles of bristles fixed in the recesses run like a chord within the base body. Due to this position of the bristle bundles at an angle to the radial and the design of the recesses adapted thereto, a base body having a relatively small outer diameter can also be provided with recesses which are designed with sufficient depth.
- the exact shape of the recesses can be created by means of inserts which can be inserted into the base body if the base body is made of wood, for example.
- the base body can be machined relatively roughly in the sections machined to accommodate the inserts, which reduces the manufacturing effort.
- the inserts which can be designed identically for a spreader roller, can be produced in large numbers and thus inexpensively.
- the recesses for different groups of bristle bundles can differ in terms of their depth, as a result of which the spring hardness of the bristles effective in the longitudinal direction of the spreader roller can be influenced.
- the spring hardness should preferably increase, starting from the transverse center plane of the spreader roller, in the direction of its two ends.
- a stretching gradient can be arranged on the treated fabric layer in such a way that the fabric layer extends from the middle of the spreader roll. stretching roller is stretched out with an almost linear increase towards the two ends of the spreader roller, which results in a very even stretching movement that promotes wrinkle removal and is also gentle on the fabric layer.
- the base body As an alternative to forming the recesses with different depths, there is the possibility of forming the base body with different diameters in partial sections in which recesses are provided, whereby the effective bristle length and thus the effective spring hardness of the bristles can also be influenced. As a result, the manufacturing effort can be reduced because all recesses of the spreader roller have the same depth.
- the bundle of bristles should rest against the second side wall of the recess when a force is applied to the bristle ends, which leads to the pivoting movement of the bundle of bristles in the longitudinal direction of the base body.
- This has a curved course, starting from the outer lateral surface of the base body.
- the interaction of the bristle bundle with the curved second side wall causes a progressive increase in its spring hardness, i.e. there is a bending force curve over the bend in which the spring hardness increases with the bending of the bristles.
- the bristle bundle subjected to a force at the bristle ends is increasingly deformed on the curved second side wall, as a result of which the free bristle length is increasingly shortened as a result of the bending of the bristles.
- the bundle of bristles is bent more severely, its greatest spring hardness occurs.
- this configuration of the second side wall it is provided that this has a course in which several differently curved areas adjoin each other.
- the curvature of the second side wall can change continuously.
- the bristles that are in contact with them are made of a low-friction material, so that they are guided to the recess on the first side walls with little friction.
- a partial area of the bristles or only the radially outer bristles can preferably be provided with correspondingly optimized sliding properties.
- the bundle of bristles with good gliding properties should be at first be guided side walls.
- the object is also achieved in that, in combination with the generic features, the bristles have a rectangular or elliptical cross section at least in their free end section, with these being arranged on the base body with their smaller side surface aligned in the circumferential direction of the spreader roller. Since the area moment of inertia increases with the third power of the expansion, even a small difference in width is enough to cause a noticeable anisotropy of the bristle movement. In this way, the effects of the trailing and the emergence of the bristles can be influenced in the usual construction of a spreader roller with slanting bristle bundles simply by the design of the cross-section of the individual bristles. In a further embodiment of this solution, it is provided that the spreader roller is driven in rotation, with its direction of rotation being opposite to a rolling movement that would result from a direction of travel of the spreader roller.
- a spreader roller should be provided for a device for smoothing a textile fabric in the area over which a spreader roller travels, with the spreader roller, which interacts with the surface of the fabric and is designed as a round brush, having a cylindrical base body with bristles fastened in it, which, to form bristle bundles summarized, tower over an outer lateral surface of the base body.
- the bundles of bristles are each arranged at a distance from one another, whereby by means of free end sections of the bristles, which grip the fabric, a longitudinal tension of the fabric can be achieved on the one hand in a direction in which there is a relative movement between the fabric and spreader roller and on the other hand by diagonally in the direction of the Ends of the base body inclined, arranged on both sides of a transverse central plane of the base bristle bundles in the interaction of the spreader roller with the Stoffla ge at this a transverse tension is achievable.
- the spreader roller should be designed according to one of patent claims 1 to 12. In the aforementioned device, the spreader roller should be driven in rotation, with the direction of rotation of a rolling movement that would result from a direction of travel of the spreader roll is opposite.
- spreader rollers can be specifically equipped with an asymmetry using the aforementioned means, for example to achieve different processing goals by selecting the direction of rotation, such as adapting the spreader roller to the respective textile.
- a change in the direction of rotation or a 180° pivotable axis of the spreader roller can be provided.
- the device is a treatment module of a laundry treatment cabinet, wherein mechanical stresses on the laundry item can be achieved by means of at least one spreader roller provided for smoothing an item of laundry to be treated in a treatment position of the treatment module.
- the treatment module is movably arranged in the laundry treatment appliance in order to effect smoothing of the item of laundry to be treated by moving the treatment module along the item of laundry to be treated with the spreader roller having contact with a layer of fabric.
- Bristles of the spreader roller are each aligned inclined away from the transverse center plane of the spreader roller. This advantageously results in the intermediate item of laundry being stretched in the width direction of the brush, which improves the smoothing effect.
- the bristles are combined into bristle bundles, for which recesses in the base body designed according to the invention achieve an anisotropic influence on the spring forces of the bristles acting in the circumferential direction and in the longitudinal direction of the spreader roller.

- FIG. 16 shows a plan view of the arrangement according to FIG. 15, and FIG. 17 shows a representation, enlarged to scale, of a bristle bundle of the round brush of FIG.
- 1 designates a spreader roller 1 which is designed as a round brush 2 and has a cylindrical base body 3 .
- bristle bundles 4 distributed uniformly over its circumference are fixed, which consist of bristles 5 and in each case protrude radially beyond a partial section of an outer lateral surface 6 of the base body 3 .
- these bundles of bristles 4, starting from both ends 7 and 8 of the base body 3 are each provided in a partial area of its longitudinal extent.
- differently inclined bristle bundles 4 run such that they each have an inclined position to the transverse plane of the base body 3 in the direction of its ends 6 and 7, respectively.
- a section 4a of each of the bristle bundles 4 is movably arranged in a recess 10 formed in the base body 3, the corresponding recess 10, as can also be seen from the side view according to FIG. 1, being provided with an outer contour in the shape of an elongated hole is, which runs with its longest extent in the longitudinal direction of the base body 3, so that the bristle bundle 4 can perform a free pivoting movement in this direction.
- This outer contour which is visible in a plan view, will be explained in more detail below with reference to FIG.
- FIGS. 3 and 4 show that the bristle bundles 4 are fixed by means of their end attachment sections 11 in an end of the respective recess 10 facing away from the outer lateral surface 6 of the base body 3 .
- the recesses 10 form, as FIGS. 3 and 4 in particular illustrate, first side walls 12 and 13, which extend in the longitudinal direction of the base body 3 and run parallel to one another, so that the recesses 10 have a slot-like outer contour at least on the outer lateral surface of the base body 3 exhibit. Consequently, the bristle bundles 4 are guided on these first side walls 12 and 13 because of their diameter which is matched to the corresponding width of the recess 10 .
- the recesses 10 which have a second side wall 15 in the direction of the respective end 7 or 8 of the base body 3 end, have such a longitudinal extension that in the exemplary embodiment the pivoting movement of the bristle bundles 4 about their fastening sections 11 is not limited in this direction.
- the course of this second side wall 15 can be seen in particular from FIG. 3, with the bristle bundle 4 in this exemplary embodiment being aligned in its unloaded state at an acute angle a to the second side wall.
- FIG. 4 shows a top view of a section of the round brush 2 in the area of one of the recesses 10, which has the slot-like course on the outer surface 6.
- the above-described shape of the recess 10 and its interaction with the bundle of bristles 4 results in its guidance in the circumferential direction and its relative mobility in the axial direction of the round brush 2, so that the bundle of bristles 4 has an anisotropic flexural rigidity. While the guidance of the bristle bundles 4 in the circumferential direction results in only a short free bristle length, which is illustrated in FIG. Gen 10 has a large free bristle length for bending in the longitudinal direction of the base body, which is denoted by a second dimension arrow 17 in FIG. 1, so that the bristle bundles 4 act with little rigidity in the longitudinal direction. As a result, the effect of the accruing bristles 5 that is desired in the longitudinal direction of the round brush 2 can be intensified in the manner required for smoothing a web of material.
- a spreader roller 27 is provided according to FIG. 2a, in which bundles of bristles 28 are arranged with a chord-like course in a base body 27a. This results in an offset 28a of the bristle bundles 28 to the center of the base body 27a.
- the recesses which also run like a chord and also have an outer contour as shown in FIG. 1, can be formed with sufficient depth in a base body with a relatively small outer diameter.
- the obliquely running bundle of bristles 14 is then moved orthogonally to the support 18 and thus to the layer of material 19.
- the angle of attack of the bristles 5 of the bristle bundle 4 results from the orthogona len movement of the bristle bundle 4 accruing movement of the free bristles 14 on the surface of the fabric layer 19, which together with the support 18 causes a Tan gentialkraft in the fabric layer.
- the tips of the bristles 5 impale themselves in the layer of material 19 and push this radially away from the clamping 11 of the bristle bundle 4 in the direction of inclination.
- the resulting force acting on the fabric layer 30 is significantly higher than the longitudinal force generated by the bristles 5 trailing behind.
- the bundle of bristles 4 shown belongs, as illustrated in FIG. roller 1 are arranged, so run obliquely in the direction of the adjacent end thereof.
- Another group of bristle bundles 4, which also act in the manner described above, runs with an opposite inclination.
- the running bristle movement generated at the two differently running groups of bristle bundles stretches the fabric layer 19 so that the creases and folds running in the longitudinal direction of the fabric layer 19 are removed.
- FIG. 6 shows the effect occurring on the individual bundle of bristles 4, which occurs on the bundle of bristles 4 as a result of the circumferential movement of the rotary-driven spreader roller 1 and its movement.
- the ge on the surface of Stoffla 19 touchdown bristle ends 14 produce at this a tangential to the spreader roller 1 extending tensile force, which is used to remove running in the transverse direction of the fabric layer 19 wrinkles and folds.
- FIG. 7 Another embodiment of recesses 20, which can also be arranged in the manner shown in FIG. 1 in the base body 3, is shown in FIG. 7.
- Side wall according to FIG. 7 is provided with a curved second side wall 21.
- the recess can also have a slot-like cross section as shown in FIG.
- a bundle of bristles 22 is intended to come into contact with the second side wall 21 during its pivoting movement.
- the curved second side wall 21 causes a progressive increase in the spring hardness of the bristle bundle 22 when this is progressively deformed on the second side wall 21 .
- the bundle of bristles is also as previously explained in this exemplary embodiment 22 is movably arranged in the recess 20 with its section 22a.
- a certain spring force acts on the bundle of bristles 22 fixed to its fastening section 11, with the free bristle length determining the spring stiffness acting on bending.
- This free bristle length decreases as the force applied to the bristle ends 14 increases.
- the free bristle length is shortened by the bend. Characterized occurs at a maximum bending of the bristle bundle 22 on this second side wall 21 on the greatest spring hardness.
- this bundle of bristles 26 is designed like a crescent moon, viewed in cross section.
- a bending angle ⁇ is plotted on an abscissa and a bristle hardness b H is plotted on an ordinate.
- a line 29 running parallel to the abscissa illustrates a bristle hardness b H that is constant over the entire bending angle ⁇ , as is the case when the recess 10 is formed according to FIG.
- the changing bristle hardness b H over the bending angle ⁇ is illustrated by means of a curve 30, as it comes about in a configuration of the recess 20 according to FIG. In this case, the bristle hardness b H changes progressively with increasing deformation of the bristle bundle 22, as already explained above.
- the individual bristles 5 of the bristle bundles 4 or 22 with a cross section that deviates from the circular shape.
- a rectangular cross section 31 of the individual bristles 5 is provided, where the smaller side surface 32 of the rectangular bristle should be oriented in the circumferential direction of the spreader roller 1 .
- the situation is similar when using bristle bundles with bristles that have an elliptical cross section 33, in which case these should then point in the circumferential direction with their smaller side surface 34, where the elliptical cross section has its smallest radius.
- the process can be dynamically guided according to the measured values along suitable parameter combinations, adapted to the respective work situation.
- a significant centrifugal force can be selectively induced on the bristles 5 via higher speeds of the spreader roller 1, as a result of which they introduce an additional radial force into the fabric layer 19 when they are placed on it.
- FIG. 12 shows a schematic representation of a laundry treatment appliance 35 .
- This laundry treatment device 35 should have a treatment chamber, not shown in detail, in which a shirt 36 is hung up via a hanging device 43 (see FIGS. 13 and 14). This is subjected to a smoothing process in the treatment chamber to remove wrinkles/creases.
