Abstract
The machine includes a device for spreading a wrapping sheet and an elevator, adapted to move a roll to be wrapped with respect to the wrapping sheet, so as to wrap the wrapping sheet around the roll as a result of the movement between the wrapping sheet and the roll. The machine further includes members adapted to reduce the formation of creases in the wrapping sheet during the movement of the roll with respect to the wrapping sheet.
Claims20
A machine for packaging rolls, comprising
- wrapping sheet feed members;
- an elevator, adapted to move a roll to be wrapped with respect to the wrapping sheet, so as to wrap the wrapping sheet around the roll as a result of movement between the wrapping sheet and the roll;
- a first lateral wall and a second lateral wall approximately parallel to the first lateral wall;
- wherein the elevator is vertically movable between the first lateral wall and the second lateral wall;
- and
- members adapted to reduce formation of creases, said members being integrally connected with the elevator and move vertically with the elevator, in the wrapping sheet during movement of the roll with respect to the wrapping sheet.

- members adapted to reduce formation of creases, integral with the elevator, in the wrapping sheet during movement of the roll with respect to the wrapping sheet;
- and
- wherein the members adapted to reduce formation of creases comprise a first plate integral with the elevator and approximately parallel to said first lateral wall and said second lateral wall;
- wherein the first plate extends downward away from a seat for housing the roll, integral with the elevator;
- wherein the first plate defines, with a respective one of the first lateral wall and the second lateral wall with which the first plate is parallel, a first gap configured to receive therein a first flap of the wrapping sheet during lifting movement of the elevator.

- an elevator, adapted to move a roll to be wrapped with respect to the wrapping sheet, so as to wrap the wrapping sheet around the roll as a result of movement between the wrapping sheet and the roll;
- a first lateral wall and a second lateral wall approximately parallel to the first lateral wall;
- wherein the elevator is vertically movable between the first lateral wall and the second lateral wall;
- and
- members adapted to reduce formation of creases, integral with the elevator, in the wrapping sheet during movement of the roll with respect to the wrapping sheet;
- wherein the members adapted to reduce formation of creases comprise, on at least one side of the elevator, a crease reducer member oriented from the elevator toward one of said first lateral wall and said second lateral wall, and arranged so that when the elevator lifts the roll toward the wrapping sheet, said wrapping sheet is interposed between the crease reducer member and said one of said first lateral wall and said second lateral wall, the crease reducer member generating a contact force on the wrapping sheet and against the one of said first lateral wall and said second lateral wall at least during a lowering step of the elevator;
- wherein the members adapted to reduce formation of creases further comprise a first plate integral with the elevator and approximately parallel to said first lateral wall and said second lateral wall;
- wherein the first plate extends downward away from a seat for housing the roll, integral with the elevator;
- wherein the first plate defines, with a respective one of the first lateral wall and the second lateral wall with which the first plate is parallel, a first gap configured to receive therein a first flap of the wrapping sheet during lifting movement of the elevator;
- and wherein the first plate extends below the crease reducer member.

A method for wrapping a roll in a wrapping sheet, comprising steps of:
- arranging a roll on an elevator positioned between a first lateral wall and a second lateral wall and movable therebetween;
- arranging a wrapping sheet on an approximately horizontal plane, which intersects a trajectory of movement of the elevator between the first lateral wall and the second lateral wall;
- lifting the roll by the elevator against the wrapping sheet so as to partially wrap the roll with the wrapping sheet, generating two flaps of the wrapping sheet extending below the elevator;
- wrapping the two flaps of the wrapping sheet around the roll;
- wherein, during relative movement between the elevator and the wrapping sheet, a flattening action is exerted on at least one of said two flaps of the wrapping sheet by a member to reduce creases which is integrally connected with the elevator and moves vertically with the elevator.

- and wherein during lifting of the elevator, at least one of said two flaps of the wrapping sheet is inserted into the first gap;
- said first plate being substantially parallel to the respective one of the first lateral wall and the second lateral wall with which the first gap is formed.
