- EP-B-0757728 describes a machine for the continuous processing of textile fabric by means of a brush made of synthetic filaments charged with aluminum or carbon, of which an hypothetical abrasive capacity is claimed.
- the textile fabric is subjected to the abrasive action of the rotating member - which may be a brush, a cylinder covered with abrasive paper or abrasive cloth, a body integrally made of abrasive material or the like - by tensioning the fabric and putting it into contact with the rotating abrasive member.
- the rotating member which may be a brush, a cylinder covered with abrasive paper or abrasive cloth, a body integrally made of abrasive material or the like - by tensioning the fabric and putting it into contact with the rotating abrasive member.
- Tensioning the material causes a number of problems, particularly due to the formation of folds or creases in the longitudinal direction which leads to the fabric being processed in different ways along its transversal development.
- the tension induced in the fabric may also alter the structure of the warp and weft yarns with consequent processing irregularities.
- Some yarns are subjected to more abrasion than others causing the formation of irregularly distributed lines on the finished product, in correspondence to where the fabric was excessively consumed by the abrasive member and appears to have lost essentially all its color.
- the loose or taut selvages subjected to tension by traditional grinding machines cause problems related to variable degree of abrasion which affects processing quality.
- object of the present invention is the realization of a new method and machine to overcome the aforesaid problems. More in particular, object of the invention is the realization of a machine for processing - specifically abrasion processing - textile materials or other continuous web material without inducing tensions in the web material which may negatively affect the final processing result.
- the cylindrical member is associated to a mobile guiding element on which the web material is guided, whose position varies with the contact arch between the web material and the cylindrical member; and in that the speed of at least one of said feeding and distancing means is controlled according to the position of said mobile guiding element.
- the contact angle or arch between the fabric or other continuous web material around the rotating cylindrical member can be controlled without excessively tensioning the web material or even practically without tensioning the web material at all. This avoids the formation of creases or longitudinal folds and provides uniform processing on the entire width of the material being processed.
- the invention is based on the idea of exploiting the attitude that the web material would assume if it were fed freely into contact with the rotating cylindrical member.
- This variable attitude is caused by the abrasive surface of the rotating member which in contact with the web material tends to withhold it on its surface and drag it making it turn.
- This attitude varies according to: > the rotation speed of the rotating cylindrical member
- the effect of the treatment can be varied without inducing critical tension in the web material by maintaining the characteristics of the rotating member and the web material and changing the speed of the rotating member and the feeding speed and/or the distancing speed of said web material to or from said rotating member.
- an encoder or potentiometer or other suitable detecting means associated to the mobile guiding element generates a signal for modifying the feeding speed or the pulling speed of the web material to or from the rotating cylindrical member. After setting the required position of the guiding element (and consequently setting the contact arch between the web material and the rotating cylindrical member) this attitude, which corresponds to a certain abrasive effect, can be maintained by means of a feedback signal generated by the encoder or potentiometer.
- the position of the guiding element is used to control the speed of the distancing mean of the web material instead of the feeding mean.
- the speed of the web material is controlled at the rotating cylindrical member output. A more accurate control is obtained in this way.
- the peripheral speed of the rotating cylindrical member can differ from the feeding speed of the web material around it according to modulus and/or direction.
- the cylindrical member may turn at a peripheral speed which in the same direction as the advancement of the web material.
- the difference in speed is obtained by adopting a peripheral speed of the rotating member whose modulus is different (preferably higher) than the feeding speed of the web material.
- the guiding element can advantageously be arranged upstream to said rotating cylindrical member with respect to the direction of advancement of the web material on said advancement path.
- the cylindrical member can turn at a peripheral speed whose direction is opposite to that of the direction of advancement of the web material around it.
- the member can advantageously turn at a peripheral speed whose modulus exceeds the speed of advancement of the web material to increase the difference in speed between the material to be processed and the periphery of the cylindrical member.
- the guiding element is advantageously arranged upstream to the cylindrical member.
- the guiding element is on the side of the cylindrical member towards which the cylindrical member tends to drag the web material by effect of the friction between the cylinder and the textile fabric.
- two or more rotating cylindrical members can be arranged along the path of advancement of the web material.
- a guiding element and respective means for feeding and distancing the material are advantageously associated to each cylindrical member. It is understood that the distancing means of the web material from a cylindrical member can be formed by the (or part of the) means used for feeding the web material to the following cylindrical member.
- a multiple cylindrical member configuration it is suitable to provide that the control priority of the distancing means associated to most downstream cylindrical member is higher than that of the other distancing means of the upstream members, which are subjected to the control of the means which are more downstream.
- a master-slave type control is implemented, where the master is the most downstream cylindrical member. In the case of more than two rotating cylindrical members, the master-slave arrangement is repeated in each consecutive cylindrical member pair.
- the guiding element (or each guiding element, in the case of multiple arrangement) can consist of a dancer cylinder movable e.g. along a straight trajectory, and suitably guided.
- the guiding element is supported by an articulated pivoting arm on the axis of rotation of said rotating cylindrical member.
- the pivoting arm may be counterweighted, e.g. with a suitable counterweight carried by a flexible member, such as chain or the like, entrained around a wheel which is integral with the pivoting arm.
- a high velocity cylinder-piston system may be used to rapidly change the counterweight value.
- the guiding element does not apply a high tension on the web material by applying a counterweight to the pivoting arm.
- high tension is used to indicate a tension which may cause an alteration in the processing effect of the fabric, e.g. due to the formation of creases or folds in the fabric and/or due to the alteration, which may also be only temporary, of the warp and weft of the fabric.
- the guiding element may be suitably associated to position detecting sensor members which detect the position thereof.
- the speed of the distancing means is therefore controlled by a suitable control unit in such a way as to avoid applying high tension to the web material.
- the mean for distancing the web material from the cylindrical member is controlled by the position of said guiding element so that the contact angle between the web material and the cylindrical member does not exceed a pre-settable value.
- the rotating cylindrical member can be any type of member, for performing any operation on the web material.
- the invention can be used to obtain particular advantages when the rotating cylindrical member is an abrasive member, specifically a cylindrical brush with abrasive bristles.
- the abrasive bristles can consist of synthetic material filaments charged with granules of abrasive material.
- the invention also concerns a method for the continuous processing of web material, specifically textile fabric, comprising the following phases: feeding the web material along a feeding path and around a rotating essentially cylindrical member which processes said web material; distancing the web material from said cylindrical member.
- the method is characterized in that the speed at which the web material is fed and/or distanced from the cylindrical member is controlled according to the contact arch between the cylindrical member and the web material.
- the method according to the invention provides for: arranging a mobile guiding element for the web material along the feeding path next to the cylindrical member; detecting the position of the mobile guiding element with respect to the cylindrical member; and controlling the speed at which said web material is distanced and/or fed to the cylindrical member according to the position of the mobile guiding element.
- FIG. 1 schematically shows an abrasive rotating cylindrical member working on a fabric which is not tensioned, without the use of the measures provided by present invention
- FIG. 2 schematically shows the structure of a machine according to the invention with a single rotating cylindrical member
- Fig. 3 schematically shows a machine according to the invention with two rotating cylindrical members turning in opposite directions
- Fig. 4 schematically shows a machine similar to that illustrated in Fig. 3, with two abrasive rotating cylindrical members, but in a configuration suitable for processing both sides of the web material. Detailed description of the invention
- Reference numeral 1 in Fig. 1 very schematically indicates an abrasive rotating cylindrical member, specifically an abrasive cylindrical brush in this example.
- the cylindrical member turns on an axis A in the direction indicated by the arrow fl .
- Reference 1A indicates a clothing, for example, made of filaments of synthetic material charged with abrasive particles, e.g. TYNEX ® filaments.
- a textile fabric T advancing the arrow fT is guided around the rotating cylindrical member 1.
- the trajectory of the fabric T can vary according to the contact arch on the cylindrical member 1.
- the tension on the textile fabric T By reducing the tension on the textile fabric T, the latter is dragged downwards by the cylindrical member 1 , whose peripheral speed is higher than the speed of advancement of the fabric itself.
- Excessively low stress on the textile fabric T makes the fabric tend to wind around the rotating cylindrical member 1 , as shown by the fabric in the attitude indicated by reference T ⁇
- reference numeral 1 again indicates a rotating cylindrical member turning on an axis A.
- the rotating cylindrical member 1 for example, is made of a cylindrical brush equipped with a clothing of filaments 1A of synthetic material charged with abrasive granules.
- the textile fabric T is fed along an advancement path by a feeding mean, generically indicated by reference numeral 3 and consisting in this example of a driven cylinder 5 on which the fabric T is advanced by guiding it on two guiding rollers 7 and 9.
- a distancing mean 11 consisting of driven rotating cylinder 13 on which the fabric T is guided and a pair of guiding rollers 15 and 17 (similarly as the feeding mean 3) is arranged downstream with respect to the rotating cylindrical member 1.
- Reference numerals 19 and 20 schematically indicate two independent motors for operating the driven cylinders 5 and 13 whose rotation speed may be reciprocally different.
- the rotating cylindrical member 1 is operated by a separate motor (not shown). A different configuration of the various motors may be used.
- a baffle 21 presenting a rounded edge 21 A whose curvature radius is relatively small to deviate the trajectory of the fabric to the cylindrical surface of the rotating cylindrical member 1 is arranged between the feeding means 3 and the rotating cylindrical member 1.
- the fabric T is guided on the mobile roller 25 and forms therefore a curve in the section comprised between the point of detachment between the rotating cylindrical member 1 and the guiding roller 15 of the distancing means 11.
- the assembly consisting of the pivoting arms 23 and the guiding roller
- a counterweight 27 fastened to the lower free end of a chain 29 whose second end is fastened to chain wheel 31 integrally fastened to the arms 23 and consequently rotating on the axis A.
- two counterweights 27, two chains 29 and two chain wheels 31 fastened to the two counterpoised arms 23 can be provided.
- the pivoting movement of the arms 23 causes more or less winding of the chain 29 on the respective chain wheel 31.
- the counterweight 27 nearly entirely eliminates the tension due to the weight applied by the guiding roller 25 on the fabric T.
- a position sensor e.g. an encoder or potentiometer, schematically indicated by reference numeral 33 in Fig. 2, is associated to the assembly formed by the pivoting arms 23 and the guiding roller 25.
- the encoder 33 interfaces with a control unit 35, which in turn interfaces at least with the motor 20 and possibly with the motor 19.
- the control unit 35 by suitably programming the control unit 35, the angular position of the pivoting arms 23 and the guiding roller 25 (and consequently the contact arch between the fabric T and the rotating cylindrical member 1) can be corrected by varying the speed with which the driven cylinder 13 pulls the fabric from the cylindrical member 1.
- the speed of the driven cylinder 13 is temporarily increased to pull the fabric T and consequently reduce the loop formed between the rotating cylindrical member 1 and the guiding roller 15.
- An opposite correction can be applied when the contact angle between the fabric T and the surface of the rotating cylindrical member 1 is excessively small, i.e. when the position of the pivoting arms 23 is excessively high.
- two limit angular positions can be defined in correspondence with which the correction by temporary acceleration of the motor 20 is either started or stopped.
- the encoder 33 may be replaced by two limit switches which start and stop the acceleration control.
- a plurality of micro switches or proximity sensors arranged along the trajectory of the pivoting arms 23, e.g. a plurality of capacitance, magnetic or linear sensors, to detect the passage of one of the two pivoting arms 23 and consequently control the acceleration or deceleration of the motor 20 associated to the driven cylinder 13.
- Fig. 3 shows a form of embodiment of the machine according to the invention with two rotating cylindrical members, consisting of abrasive cylindrical brushes also in this case.
- Equal numbers indicate parts which are either equal or corresponding to those illustrated in the previous form of embodiment.
- the machine comprises two consecutive sections, indicated by references 51 A and 51 B.
- Section 51 A is essentially equal to the machine in Fig. 2. It presents a brush 1 with bristles 1 A, means 3 for feeding the textile fabric T, distancing means 11 , a guiding element consisting of the roller 25 and the respective supporting pivoting arm 23.
- Each of the feeding and distancing means are equipped with respective motors 19 and 20, in this case shown in axis with the corresponding driven cylinders 5 and 13.
- the bristles 1A of the cylindrical brush 1 are slanted with respect to the radial direction and more exactly are slanted backwards with respect to the feeding direction of the fabric T and to the direction of the rotation of the brush. This ensures the best abrasive results because the granules incorporated in the synthetic resin which forms the bristles projects from the edges of the bristles.
- Section 51 B has in common with section 51 A the arrangement of the means 11 forming the feeding means of the fabric T to a second rotating cylindrical member, indicated by reference numeral 101 , and consisting of a cylindrical brush with bristles 101 A.
- Members equivalent to the members in the upstream section are associated to the brush 101 , namely a guiding roller 125 supported by a pair of arms 123 hinged on axis B of rotation of the brush 101.
- An encoder or potentiometer 133 provides a signal indicating the angular position of the arms 123 and consequently the contact arch of the fabric T with the brush 101.
- Reference 121 indicates a baffle of the fabric and references 111 , 113, 115, 117, 120 indicate the members forming the means for distancing the web from the second brush 101 , equivalent to the means 11 , 15, 17, 20.
- the arms 123 and the guiding roller 125 are balanced by a counterweight 127 supported by a flexible member 129 similar to the flexible member 29, turning around a wheel 131 which is integral with the arms 123 and coaxial to the axis B.
- the angular position of the arms 123 is detected by an encoder 133.
- the arrangement of the section 51 B differs with respect to the arrangement of the section 51 A, in that the brush 101 turns in the direction opposite to that of the brush 1. Consequently, the direction of the peripheral speed of the brush is opposite to the speed of advancement of the fabric in the contact area between the fabric T and the brush 101. Consequently, the direction in which the bristles 101 A are slanted is also reversed.
- the guiding roller 125 is arranged upstream to the brush 101 with respect to the direction of advancement of the fabric T.
- the motors 19, 20, 120 and the encoders 33, 133 interface with a programmable central control unit 35 which is similar to the unit 35 in the previous example of embodiment.
- the operation is illustrated below.
- the arms 123, 23 are in an intermediate position, in an acceptable angular range. If the fabric T tends to wrap excessively around the brush 101 A on input side (i.e. towards the feeding means 11 to section 51 B) by effect of the dragging exerted by the abrasive bristles 101 A, the distancing means 111 are consequently accelerated to pull the fabric.
- Section 51 A works in the way already described with reference to the machine in Fig. 1 , with the difference that it is subordinated to the control of section 51 B. In other words, the distancing speed of the means 11 from section 51 A is corrected after correcting the speed of the means 111 , to return the arm 123 to the correct position.
- Fig. 4 shows a form of embodiment which is similar to that shown in
