MACHINE FOR MAKING ABSORBENT SANITARY ARTICLES

摘要

A machine for making absorbent sanitary articles includes a device for feeding a continuous strip to a conveyor roller and to a device for cutting the strip into first and second pieces. A unit forms and applies at least a pair of first and second pieces, aligned and spaced by a distance (d), for each absorbent article. A first and a second roller each comprising a plurality of units pick up and successively release of first and the second pieces. A plurality of concentric units rotating, independently of each other, about a shared axis of rotation, each carries at least one unit. A motor defines a respective law of motion for each of the units and a mechanism translates the units, between a position for picking up the pieces, at the conveyor roller, and a position for releasing the pieces, at the forming and applying unit.

主权项

1. A machine for making absorbent sanitary articles, comprising
a device for feeding a continuous strip to a conveyor roller, rotating about an axis parallel to a first reference direction, a device for cutting the strip in a continuous and alternating succession of first rand second pieces, comprising, respectively, first and second accessory elements of the absorbent article, a unit for forming and applying on a continuous band of absorbent material, fed by a conveyor along a second direction at right angles to the first, at least a pair of accessory elements for each absorbent article, comprising the first and the second piece aligned and spaced at a distance along the first direction; a device for cutting the continuous band into pieces of absorbent material designed to constitute single absorbent articles, following application of the accessory elements, a first and a second roller rotating about respective axes parallel to the first direction and each equipped with a plurality of units for picking up, respectively, the first and the second pieces, from the succession and their release on the forming and applying unitthe machine being characterised in that each transfer roller comprises
a plurality of concentric units rotating independently of each other about a shared axis of rotation, each of the units carrying at least one unit, motor means for defining a respective of motion for each of the units, and means for translating the units along a direction parallel to the first direction, between a position for picking up the pieces, at the conveyor roller, and a position for releasing the pieces, at the forming and applying unit.
