Abstract
A machine (1) for spreading fabric on a spreading plane (2) includes a carriage (3) that is movable on the spreading plane, the carriage has an unwinding system (6) for unwinding the fabric; an inclined chute arranged below; a cutting system (11) for cutting the fabric, arranged at a lower end (12) of the chute; and a movement system (35) for moving the unwinding system between a first and a second unwinding operating configuration. In the first configuration, a first end (14) of the unwinding system is vertical to the chute (10) and in the second configuration, the first end (14) is in an advanced position towards the cutting head (13).
Claims17
A machine for spreading fabric on a spreading plane, comprising a carriage that is movable on the spreading plane with rectilinear forward-backward motion along a spreading direction, the carriage comprising:
- an unwinding system comprising at least a first member adapted to set into rotation a roll of fabric so as to unwind the fabric;
- an inclined chute arranged at a lower level of at least one portion of the first member,
- a cutting system for cutting the fabric, arranged at a lower end of the inclined chute and comprising a cutting head,
- wherein the unwinding system has a first end and a second end proximal to and distal from said cutting system, respectively, said first end being adapted, in use, to drop unwound fabric downwards,
- wherein said carriage comprises a movement system adapted to move said unwinding system between at least a first unwinding operating configuration and a second unwinding operating configuration, wherein the movement system comprises a movable support mounted on a base of the carriage and moveable relative to said base along a rectilinear trajectory parallel to said spreading direction, wherein said unwinding system is mounted onto said movable support,
- wherein, in said first unwinding operating configuration, said first end of the unwinding system is vertically over said inclined chute, and
- wherein said first end is located horizontally closer to said cutting head in the second unwinding operating configuration than in the first unwinding operating configuration.

- an unwinding system comprising at least a first member adapted to set into rotation a roll of fabric so as to unwind the fabric;
- an inclined chute arranged at a lower level of at least one portion of the first member;
- a cutting system for cutting the fabric, arranged at a lower end of the inclined chute and comprising a cutting head;
- wherein the unwinding system has a first end and a second end proximal to and distal from said cutting system, respectively, said first end being adapted, in use, to drop unwound fabric downwards;
- wherein said carriage comprises a movement system adapted to move said unwinding system between at least a first unwinding operating configuration and a second unwinding operating configuration;
- wherein, in said first unwinding operating configuration, said first end of the unwinding system is vertically over said inclined chute, and in said second unwinding operating configuration, said first end is located closer to a position vertically over said cutting head with respect to the first unwinding operating configuration;
- and
- wherein in said first unwinding operating configuration, said first end of the unwinding system is vertically above a point of said inclined chute having a distance, from an upper end of said inclined chute, less than or equal to half of a total length of said inclined chute along a direction of advancement of the fabric along a chute plane, said distance being taken along said chute plane of said inclined chute, and wherein in said second unwinding operating configuration, said first end is vertically over a point on an auxiliary chute of said cutting system, wherein the auxiliary chute is placed proximate said cutting head upstream of the cutting head with respect to the direction of advancement of the fabric.
