Device for removal of trimmings in the production of rolls of web material

A device for removal of trimmings obtained from cutting a log of web material by means of a log cutting machine having at least one cutting blade for log cutting and at least one supporting surface disposed downstream of the cutting blade for supporting cut rolls, comprising:

• a conveyor for conveying rolls away from the supporting surface, said conveyor including:
• a fixed rotatable pulley,
• an upper movable roller above the pulley,
• a lower movable roller below the pulley,
• a conveyor belt extending around the lower movable roller, the pulley, and the upper movable roller,
• the upper movable roller being movable toward and away from said supporting surface to provide a variable gap between the conveyor and said supporting surface,
• the upper movable roller being movable away from said pulley as the upper movable roller moves toward said supporting surface and being movable toward said pulley as the upper movable roller moves away from said supporting surface,
• the lower movable roller being movable toward said pulley as the upper movable roller moves toward said supporting surface and being movable away from said pulley as the upper movable roller moves away from said supporting surface, whereby the length of the belt between the upper and lower movable rollers remains constant as the upper and lower movable rollers move.
