Abstract
A unit for supplying a strip to a user machine, the unit being located along a supply path of the strip, having an input for a first strip of a running-out reel and for a second strip of a new reel, and having two splicing rollers located downstream from the input and on opposite sides of the supply path to butt splice the first and second strip; a first roller of the two rollers defines an end portion of a casting path along which to cast the second strip and extending between the input and the first roller, and provides for casting a leading end portion of the second strip towards the output of the unit in time with a trailing end portion of the first strip.

A unit for supplying a strip to a user machine, the unit (1) comprising at least one input (3) for a first strip (2a) of a running-out reel (5a) and for a second strip (2b) of a new reel (5b), two splicing rollers (12) located downstream from the input (3) along a supply path (P1) of the first strip (2a) and on opposite sides of the first strip (2a);
- the two rollers (12) defining an output (4) for the first strip (2a) from the unit, and providing for butt splicing the two strips (2);
- and accumulating means (10) for accumulating said second strip (2b) and defining a casting path (P2) for the second strip (2b), said accumulating means (10) comprising a fixed portion (31) defined by a lateral wall (20) of said unit (1) and a movable portion defined by a lateral portion (32) of a first roller (12b) of said two rollers (12);
- and a lid (21) having a lateral frame (26) defining said input (3).
A unit for supplying a strip to a user machine, the unit (1) comprising at least one input (3) for a first strip (2a) of a running-out reel (5a) and for a second strip (2b) of a new reel (5b), and two splicing rollers (12) located downstream from the input (3) along a supply path (P1) of the first strip (2a) and on opposite sides of the first strip (2a);
- the two rollers (12) defining an output (4) for the first strip (2a) from the unit, and providing for butt splicing the two strips (2);
- accumulating means (1) for accumulating said second strip (2b) and defining a casting path (P2) for the second strip (2b);
- said accumulating means (10) comprising a fixed portion (31) defined by a lateral wall (20) of said unit (1);
- and a movable portion defined by a lateral portion (32) of a first roller (12b) of said two rollers (12);
- said first roller (12b) comprising stop means (39) for a leading end portion (9) of said second strip (2b);
- said stop means (39) being movable with respect to said movable portion, to and from an extracted stop position in which the stop means is located outside the lateral portion (32) of said first roller (12b).
A unit for supplying a strip in a user machine, the unit (1) comprising at least one input (3) for first strip (2a) of a running-out reel (5a) and for a second strip (2b) of a new reel (5b), and two splicing rollers (12) located downstream from the input (3) along a supply path (P1) of the first strip (2a) and on opposite sides of the first strip (2a);
- the two rollers (12) defining an output (1) for the first strip (2a) from the unit, and providing for butt splicing the two strips (2);
- accumulating means (10) for accumulating said second strip (2b) and defining a casting path (P2) for the second strip (2b);
- said accumulating means (10) comprising a fixed portion (31) defined by a lateral wall (20) of said unit (1);
- and a movable portion defined by a lateral portion (32) of a first roller (12b) of said two rollers (12);
- said first roller (12b) comprising stop means (39) for a leading end portion (9) of said second strip (2b);
- said accumulating means further comprising retaining means (29) for retaining said second strip (2b) in a casting portion along said casting path (P2);
- said retaining means (29) comprising a movable part (37) associated with said first roller (12).
