Description

MACHINE TO EXTEND LAMINAR PRODUCTS The present invention relates to a machine for extending laminar products from a roll in which a laminar product is rolled. The present invention relates more concretely to a machine for spreading one or more layers of fabric on a paper layer.

BACKGROUND OF THE INVENTION Known are machines for extending fabric from a roll of fabric comprising means for feeding the rolled laminar product and means for conducting the laminar product which facilitate its exit and conduct it on the table in which it extends. The mentioned mechanisms are mounted on a sliding carriage along the table. The carriage, when deployed, extends the fabric on the table until it reaches the end of it, where a fold is cut or formed by inverting the direction of the displacement of the carriage, which extends a second layer of the carriage. fabric over the existing layer, and so on. The machine can then extend one or more layers of fabric along the table as appropriate in each particular application.

In many cases there is a need to spread a layer of separating paper for each certain number of layers of extended fabric, leaving a certain number on the work table and alternating vertically. of groups of fabric layers and separating paper layers. Until now, the procedure followed to put these layers of paper separators was done completely manually, leaving the cart to extend fabric stopped at one end of the table until the operator spoke and cut the corresponding paper layer. Then, the automatic extension of the fabric with the car was resumed, until a layer of paper was needed. This procedure was followed until the end of the extension, which entailed a great loss of time compared to the time spent in extending tissue in an automated way.

DESCRIPTION OF THE INVENTION With the machine of the invention, the aforementioned drawbacks can be solved by presenting other advantages that will be described. The machine for extending laminar products of the invention is characterized in that it comprises a second roll in which a second laminar product is wound, means for actuating said second roll and control means that allow to control in manual or automatic mode. the extension of the two laminar products on the table according to parameters such as the cadence in the extension of the second laminar product with respect to the first and the length of the layer of the second laminar product. Thanks to this feature, it is possible to extend the first laminar product, the second laminar product or both at the same time in a totally automatic and controlled way, avoiding that the operator has to put the cloth with his hands. Advantageously, the machine of the invention comprises cutting means of the laminar product (s). According to one embodiment, the driving means of the second roll are motorized rollers. According to a second embodiment, the drive means of the second roll is a motorized shaft coupled to the second roll. According to a third embodiment, the driving means of the second roll are feeding bands.

According to a fourth embodiment, the drive means of the second roll is a motor that drives the roll axis by means of a transmission mechanism. Advantageously, the machine of the invention comprises a driver cylinder that facilitates the exit of the laminar product from the second roll. Preferably, the machine of the invention comprises a pressing cylinder that presses against the cited conductive cylinder, so that the second laminar product is dragged between the two cylinders. Q Advantageously, the machine of the invention comprises means for detecting the tension of the second laminar product. Preferably, the machine of the invention comprises at least one plate on which the laminar products slide. Advantageously, the machine of the invention comprises means for detecting the position of the second laminar product. Preferably, the means for detecting the position of the second laminar product are located at the beginning of the plate on which the laminar products slide. Also preferably, the means for detecting the position of the second laminar product is a toelectric cell 5.

The second roll of laminar product can be arranged in different positions. According to one embodiment, the second roll of sheet product is located above the line marking the path of the first sheet product from the first roll to the table, and according to another embodiment, the second roll of sheet product is located by under the line that marks the path of the first product lick from the first roll to the table.

DESCRIPTION OF A PREFERRED EMBODIMENT As can be seen in figure 1, the machine for extending laminar products comprises a first roll 1 of fabric 2, which slides on a first plate 4 and on a second plate S conductors. In the second plate 5 is placed on the tissue 2 paper 10 from a second roll 9. The set of the fabric 2 and the paper 10 is led by the second plate 5 on a table 7. Once placed the desired length of tea . 2 and paper 10 on the table 7, a cutting element 8 cuts the fabric assembly 2 and the paper 10. In the embodiment shown in Figure 1 the first roll 1 is driven by a pair of bands 3 and the second roll is driven by a pair of motorized cylinders 6. The operation of the embodiment shown in Figure 2 is the same as in the embodiment described with respect to Figure 1. In this case at the exit of the second roll 9, the paper 10 passes through a conductive cylinder 14 that facilitates its exit and by a rocker 16 that controls the tension of the paper 10. This rocker 16 also comprises - a sensor (not shown) that controls the lack of paper? In this second embodiment of the invention, the second roll is driven by its own axis 11, which is motorized and activates its rotation. As already mentioned with respect to the embodiment -represented in Figure 2, the operation of a third embodiment of the invention, represented in Figure 3, is also the same as in the embodiment described with respect to Figure 1. In this case, the second roll 9 of laminar product 10 is located below the line - marking the path of the first laminar product 2 of the first roll 1 to the table 7. Upon leaving the second roll 9, the paper 10 passes -by the conductive cylinder 14 mentioned when describing the embodiment shown in figure 2. This cylinder 14 is pressed by a pressing cylinder 15, so that the paper 10 is dragged between the two cylinders 14, 15, and the pressing cylinder is fixed to the first plate COR ductora 4. At the start of the second conductive plate 5 is placed a photoelectric cell 17 to detect the initiation of the paper 10, while at the exit of the second mio 9 is located a sensor 10 that detects The tension - of the paper 10. In figure 4 is represented how the substitution of the second roll 9 is carried out in the case that this is located below the line that marks the path of the first laminar product 2 from the first r_Q_ 1 to table 7. As can be seen in the figure, the first conductive plate 4 is articulated by a hinge -19, which allows the plate 4 to be raised to be able to access the second roll 9. The drive of the second roll 9 shown in FIG. 4 is represented in front elevation in the Figure 5. The rotation of the second roll 9 is driven by a motor 12 meshing by a transmission 13 with the axis of the second roll 9. The second roll 9 comprises a pair of cones the edges 20 that hold the paper and its axis comprises some -guides 21 (figure 4).

In the event that the second roll 9 needs to be guided laterally, the roll 9 may comprise a pair of side guiding blades (not shown). The machine of the invention also comprises control means (not shown) that allow to control in manual or automatic mode the extension of the two produc. laminar cysts 2, 10 on the table 7 as a function of parameters such as the cadence in the extension of the second laminar product 10 with respect to the first 2 and the length of the layer of the second laminar product 10 and other suitable parameters. It should be understood that four different systems of actuation of the rolls 1, 9 have been represented in the figures, which can be combined in any suitable way. Although in the figures only one type of machine for extending laminar producers has been shown, it is obvious that the features object of the present invention are applicable to any known laminating machine. It should also be understood that, although the embodiments shown have been described as the first woven sheet product and the second paper sheet product, the machine of the invention can be applied to spread any laminar product.
