Problems solved by technology

[0005] These known solutions are not without drawbacks, which include the need to move a structure strong enough to withstand even very heavy rolls and to be able to implement lateral movements on the order of a few centimeters
[0006] Another disadvantage of known solutions is that the structure is cumbersome to replicate if one wants to align and overlap multiple layers of material
[0009] The time and cost of scaling operations actually proves to be cost-effective only above a certain number of layers, it cannot be implemented continuously and efficiently

Embodiment Construction

[0016] Referring to the accompanying drawings, a machine for unwinding and aligning fabric strips, synthetic materials, etc. 2 supports the roll 3 of tape 4, the motorized device 5 is used to unwind the roll 3 of tape 4, and the first assembly 6 is used to read the tension of the unwound tape 4 to adjust the motorized device 5 so as to eliminate the unwound Tension around the strap 4.

[0017] The machine 1 also comprises a side slide device 7 for laterally sliding the unwound tape 4 substantially without tension so as to align it on the table 8, and a second assembly 9, the second assembly 9 is used to read the lateral deviation of the tape 4 that has been unwound.

[0018] The motorized device 5 comprises an unwinding roller 10 , rotatable about its own axis parallel to the axis of the roll 3 , on which the unwound tape 4 is partially wound.

[0019] The motorized device 5 also comprises a first motor device 11 associated with the unwinding roller 10 by means of a belt dri...

Abstract

A machine (1) for unrolling and aligning ribbons of fabrics, synthetic materials and the like, particularly for conveyor-belt cutting units and the like, comprising a supporting element (2) that supports a roll (3) of ribbon (4), a motorized device (5) for unrolling the roll (3) constituted by the ribbon (4), the machine further comprising a first assembly (6) for reading the tension of the unrolled ribbon (4) in order to adjust the motorized device (5) so as to eliminate the tension of the unrolled ribbon (4), means (7) for the lateral sliding of the unrolled ribbon (4), which is substantially free from tensions, for its alignment on a worktable (8), and a second assembly (9) for reading the lateral deviation of the unrolled ribbon (4).

Description

technical field [0001] The invention relates to a machine for unwinding and aligning fabric strips, synthetic materials, etc., especially for conveyor belt cutting units and the like. Background technique [0002] In the field of producing products made of synthetic materials, CNC cutting is carried out in single or multiple layers on conveyor belt machines. [0003] The material to be processed is usually supplied in rolls which are wound with imperfect alignment. Therefore, in order to feed a CNC cutting machine, the strip material unwound from the roll must first be aligned. [0004] Currently, the most commonly used known solutions for cutting tables or for extension units that prepare several layers of material mats and then place them on the cutting machine basically use a system based on the Feedback from alignment sensors on the edges moves laterally the support on which the roll rests, correcting deviations caused by uneven winding of the roll of web material. ...
