Problems solved by technology

However, this passive unwinder does not have the possibility of precise angular alignment and centering of the material strip with respect to the cutter belt
In particular, in passive unwinders of this known type, a uniform unwinding of the strip of material is not ensured, and this can lead, especially in the case of particularly wide strips, to Asymmetrical unwinding, i.e. unwinding with significant angular deviation which in turn leads to inefficient processing of layer packs, leading to significant waste of material

Embodiment Construction

[0026] With reference to the figures, a strip support and alignment device, in particular for a strip to be cut in a cutting machine, is generally indicated with the reference number 1 .

[0027] According to the invention, the strip support and alignment device 1 comprises:

[0028] - a sheet 3 extending between a station 5 for feeding at least one strip (not shown) and a station 7 for processing the strip, defining a support and alignment surface 17 for said strip,

[0029] - first means 9 for securing the sheet 3 to the feeding station 5,

[0030] - a second device 11 for securing the sheet 3 to the processing station 7,

[0031] - means 13 for winding and unwinding the sheet 3 , adapted to wind or unwind the sheet 3 to vary its length according to the distance between the feeding station 5 and the processing station 7 .

[0032] The feeding station 5 may comprise a rack unwinding device 50, or a single or multiple such as Figures 1 to 4 The gantry unwinder 50 shown is ...

Abstract

A strip support and alignment device (1), particularly for strips to be cut in a cutting machine, the device comprising: a sheet (3) that is stretched between a station (5) for feeding at least one strip and a station (7) for processing said strip, which defines a support and alignment surface (17) for the strip, first means (9) for fixing the sheet (3) to the feeding station (5), second means (11) for fixing the sheet (3) to the processing station (7), means (13) for winding and unwinding the sheet (3), which are adapted to wind or unwind the sheet (3) in order to vary its length depending on the distance between the feeding station (5) and the processing station (7).

Description

technical field [0001] The invention relates to a strip support and alignment device in particular for the strip to be cut in a cutting machine. Background technique [0002] In the field of cutting of leather and synthetic materials used in many areas of the manufacturing industry, far-reaching changes in the technology used have been carried out over the years to reduce the time, cost and material waste associated with the cutting process, which is important throughout the production cycle. economically important. These needs therefore give rise to the requirement to provide cutting machines and related components which can be adapted in a flexible manner to the most complex and diverse machining needs and which can be controlled or programmed by electronic systems. [0003] A highly critical aspect of leather and synthetics processing involves the feeding, centering and alignment of the strips of material to be cut. [0004] Currently, known types of devices for feeding...
