## Abstract

A machine for spreading fabric. The machine includes a plurality of cylinders for guiding the fabric from the belt and a plate on which the fabric slides from the machine onto a table on which the fabric is spread out. The machine further includes a cylinder for separating the fabric, which cylinder is arranged close to the guide cylinder and is connected kinematically thereto and prevents the fabric from coming into contact with the belts in the area of discharge from the belts. The separating cylinder can be arranged in a substantially vertical position, in a substantially horizontal position or in a downwardly inclined position. The machine may also include a reversing cylinder which is arranged close to the guide cylinder and is kinematically independent thereof. The reversing cylinder enables the rotation of the roll of fabric to be reversed. The machine thus prevents the fabric from getting caught between the feed belts and the guide cylinder, thus avoiding creases and tension, and the drawing of the fabric is thereby facilitated.

## Claims

### Claim 1

A machine for spreading fabric from a roll on which the fabric is wound onto a table, said machine comprising:
a plurality of belts;
a guide cylinder which guides the fabric and which facilitates the discharge of the fabric from said belts;
a plate on which the fabric slides to be guided onto the table on which the fabric is spread out; and
a separating cylinder for separating the fabric, said separating cylinder being arranged close to said guide cylinder and connected kinematically thereto for movement with respect to said guide cylinder;
wherein said separating cylinder is movable into a position in which said guide cylinder prevents the fabric from coming into contact with said feed belts in the area of discharge from said belts.

### Claim 2 (depends on 1)

A machine as in claim 1, further comprising a reversing cylinder arranged close to said guide cylinder and mounted to rotate in a direction opposite the rotational direction of said guide cylinder.

### Claim 3 (depends on 2)

A machine as in claim 2, wherein said separating cylinder is articulated to said guide cylinder for guiding the fabric.

### Claim 4 (depends on 3)

A machine as in claim 3, wherein articulation of said separating cylinder is actuated by a motor.

### Claim 5 (depends on 3)

A machine as in claim 3, wherein said separating cylinder is movable between a substantially vertical position with respect to said guide cylinder, a substantially horizontal position with respect to said guide cylinder, and a downwardly inclined position with respect to said guide cylinder.

### Claim 6 (depends on 1)

A machine as in claim 1, further comprising means for detecting the position of said separating cylinder.

### Claim 7 (depends on 6)

A machine as in claim 6, wherein said means for detecting the position of said separating cylinder comprise a magnet arranged on a support which is integral with said separating cylinder, and a plurality of magnetic sensors which detect the presence of said magnet.

### Claim 8 (depends on 7)

A machine as in claim 7, wherein said magnet sensors are arranged in three positions which correspond to the substantially vertical position, the substantially horizontal position, and the downwardly inclined position of said separating cylinder with respect to said guide cylinder.
