A method for providing a nonlinear line of weakness on a web material including providing: a base, a support, a blade, and a driving means. The base may comprise at least one counter component having a length (L.sub.CC) where the counter component comprises a nonlinear shape having a shape width (W) and may have a plurality of teeth. The support may be operatively engaged with the base. The blade may have a length (L.sub.B) and may be disposed on the support so as to either contact or to come in close proximity with the counter component. At least one of the counter component and the blade may have a nonlinear shape.

A knife for a cutting apparatus forms incision lines and cuts on a side wall of a capsule made of plastics intended to close a container and it is suitable for performing cuts and incisions when the capsule is rotated around a rotation axis and moved along a path to interact with the knife in an advancement direction. The knife includes a vertically stacked layered structure of cutting tools. First and second spaced cutting tools form spaced circumferential cuts on the side wall and a third cutting tool arranged between the first and second cutting tools forms oblique cuts on the side wall defining connecting portions connecting the tamper ring and the side wall.

Printing and perforating machine comprising a perforating mechanism (1) and a printing mechanism (30), the perforating mechanism (1) comprising a perforating element (2, 7) provided with piercing elements (5); and a support element (4, 8) that defines with the perforating element (2, 7) a space for the passage of a sheet material (3), forming holes on the sheet material (3) when it passes through this space. With this machine, the perforation of the sheet material is carried out during the printing process thereof, preferably a digital printing, in a synchronized way, eliminating time and handling for loading and unloading the roll of sheet material in a conventional sheet material perforating machine.

Method of making a polymeric multilayer films (115) having an array of openings by coextrusion. Embodiments of polymeric multilayer films made as described herein are useful, for example, filtration and acoustic absorption.

A high-moisture-permeability, microporous plastic film randomly having a lot of recesses having different opening diameters and depths, with clefts formed in the recesses, is produced by pressing a first pattern roll randomly having a lot of high-hardness, fine particles having sharp edges on a roll body surface to a flat-surface metal roll, to produce an anvil roll randomly having a lot of recesses on a metal roll surface; arranging a second pattern roll randomly having a lot of high-hardness, fine particles having sharp edges on a roll body surface oppositely to the anvil roll; and passing a plastic film through a gap between the second pattern roll and the anvil roll.

There is provided herein a dispenser formed of card-based or paper-based material for a product in stick form. The dispenser includes a dispenser axis, a proximal end, a distal end, a product stick carrier, and a sleeve. The dispenser axis extends along a length of the dispenser. The product stick carrier is in the form of a cylindrical tube for receiving a product stick in use. The sleeve is in the form of a cylindrical tube, wherein the product stick carrier is located within the sleeve and wherein the product stick carrier and the sleeve are moveable axially relative to one another. The product stick carrier includes a cylindrical wall, a carrier proximal end, a carrier distal end and a plurality of tabs. The cylindrical wall has an inner surface and an outer surface. The product stick extends from the carrier distal end in use. The plurality of tabs extend inwardly toward the dispenser axis from the inner surface of the product stick carrier. The plurality of tabs are configured to engage a product stick supported by the product stick carrier in use to assist in securing the product stick within the product stick carrier.

A tool for manufacturing a cap for a container comprises a blade set that includes a plurality of knives. The knives are configured to make incisions in a cap having a main body having a top plate and a circular sidewall. The top plate has a top surface, wherein two opposite sides of the circular sidewall circularly connect to each other, one periphery of the circular sidewall connects to one surface of the top plate forming a closed end, and the other periphery of the circular sidewall at the opposite side of the closed end forms an opened end and a ring member, which is located at the opened end of the main body. There is a first tab on the ring member and a second tab on the sidewall.
