Problems solved by technology

[0010] Although machines are known in the prior art that can solve this problem, these machines have a very complex structure and are also very complex kinematically, since a movement influenced by the base and a further movement influenced by the anvil are required precise coordination between

Embodiment Construction

[0017] The processing device 1 receives a continuous web of elastic material 2 from a feeding station located at the feed of the processing device 1 and designated I, and which is operated and then fed out to a release station The conveyor at U, which is marked 13 in the drawing.

[0018] More precisely, the processing device 1 cuts the material web 2 into material lengths 3 and then releases the material lengths 3 to the conveyor 13 in a predetermined and desired orientation.

[0019] Preferably, the conveyor 13 is a conveyor belt, shown only partially in the figures, for feeding the continuous row 14 of finished diapers at speed v2. After application to the diaper, the material segments 3 of the material web 2 constitute the elastic waistband of the diaper.

[0020] The material sections 3 of the elastic material web 2 must be applied to each diaper in the row 14 of diapers at the same position, for which purpose each section 3 of material must be released onto the row 14 o...

Abstract

The device for processing a web of material for making nappies according to this invention comprises a rotary shaft (4) defining a first axis of rotation (A), a plurality of pads (5) for receiving and holding down the web (2) to be handled from a feed station (I), at the infeed of the device (1 ), to a conveyor (13) at a release station (U) at the outfeed of the device (1 ); the pads (5) are rotatable about the first axis (A) and are movable relative to the first axis (A) during the operation of the device (1 ); a plurality anvils (6), each interposed between two consecutive pads (5), are connected as one with the rotary shaft (4) and are rotatable with it about the first axis (A); also provided are a unit (10) acting in conjunction with the anvils (6) to cut the web (2) into lengths (3), first motor means (7), mounted inside the device (1 ) and connected to the pads (5) to translate the pads (5) along a radial direction (D1 ) at right angles to the first axis (A), and second motor means (8), mounted inside the device (1 ) and connected to the pads (5) to rotate the pads (5) about a second axis (B) coinciding with the radial direction (D1 ).

Description

technical field [0001] The present invention relates to a processing device for processing a web of packaging material. [0002] More precisely, the processing device belongs to the technical field of processing continuous webs of elastic material for the manufacture of elastic waistbands for baby or adult diapers. [0003] More specifically, the present invention relates to a cutting device for cutting a continuous web of material into segments of material constituting an elastic waistband, the segments of material being properly oriented upon exiting the cutting device prior to application to the continuous diaper row of finished diapers. Background technique [0004] This prior art device comprises a drum rotating about an axis and mounted with a base for receiving and pressing the continuous web of material, and a cutter for cutting the web into individual material segments. [0005] In order to properly orient each material segment prior to release to the conveyor belt...
