An apparatus (2) for flatting, punching or stamping a material (40) introduced into the apparatus (2), said apparatus (2) comprising a first cylinder (14) provided with an outer layer configured for flatting, punching or stamping the material (40); a back-pressure cylinder (16) extending parallel to the first cylinder (14) and an adjustment mechanism (22, 22, 28, 28, 34, 34, 36) for adjusting the distance between the first cylinder (14) and the back-pressure cylinder (16). The adjustment mechanism (22, 22, 28, 28, 34, 34, 36) comprises a first contact member (22) and preferably a second contact member (22) brought into contact with the bottom portion (circumference) of the first cylinder (14). The contact member(s) (22, 22) are mounted on a structure (34, 34) being movably mounted relative to the back-pressure cylinder (16).

Methods for making an apertured composite web are disclosed. These webs may be utilized as a topsheet in an absorbent article and can provide fluid handling and softness benefits.

In an embodiment, a paint roller manufacturing system and method uses a fabric-coating applicator to apply a fabric adhesive onto a portion of a perforated paint roller cover fabric material having a plurality of perforations through which adhesive may flow, and into the plurality of perforations and into interstitial spaces of the fabric material, to yield a length of coated fabric. An inner strip and an outer strip are wound about a mandrel in offset relation. A strip-coating applicator is used to apply a strip adhesive to the outer strip as it is wound about the mandrel. Simultaneously with the step of applying the strip adhesive to the outer strip, a portion of the coated paint roller fabric material is received at the outer strip and the length of coated fabric is wound about at least the outer strip to form a paint roller tube.

An apparatus for producing sanitary absorbent articles comprising at least one perforating device of at least one web intended for making sanitary absorbent articles capable of making perforated patterns spaced apart along the extension of the web, that is, in phase. The present invention also relates to a perforating process implemented in an apparatus for producing sanitary absorbent articles.

A perforating apparatus and method includes a longitudinal cylinder axis about which a cylinder rotates. At least one shaped anvil bead is disposed on the cylinder. The cylinder including an anvil block and an anvil bead form a cavity. The cavity may be used to control the debris produced during the perforating process. A blade is disposed on a support to cooperate in contacting relationship with the anvil bead. A web is perforated as the web passes between the rotating cylinder and the support and the blade operatively engages with the anvil bead. The debris may be controlled by being drawn into the cavity prior to the point where the blade engages the anvil and, subsequently, being expelled after the point where the blade engages the anvil bead.
