Device for forming and applying at least one pair of accessory elements on a continuous band of absorbent material and machine for making absorbent sanitary articles comprising the device
Abstract:
A device for forming and applying accessory elements to a continuous band of absorbent material, includes a unit for feeding a continuous strip to a conveyor roller, a unit for cutting the strip in a continuous and alternating succession of first and second pieces, a first and a second roller rotating about respective axes parallel to the first direction, each including a movement device acting along a circumferential direction around the respective axis and configured for imparting to each unit a respective motion between positions for picking up and releasing the pieces. A unit for applying a pair of pieces to the band is equipped with a separating unit equipped with a spacer device for moving first and/or second carriages along a separating direction between close and far axial positions, wherein the spacer device includes a plurality of linear actuators each associated with a respective first carriage.
