A separation unit is provided for separating a web material having a web width along preformed lines of weakness. The separation unit includes at least a first shaft extending along a first longitudinal axis and at least a second shaft extending along a second longitudinal axis in parallel with the first shaft. The separation unit also includes at least one first protrusion element extending perpendicularly from the first shaft and being arranged to be rotatable about the first longitudinal axis, and at least one second protrusion element extending perpendicularly from the second shaft and being arranged to be rotatable about the second longitudinal axis. The separation unit further includes at least one contact element being arranged in biased abutment against at least one of the first and second protrusion elements in a direction perpendicular to the first or second longitudinal axis.

The present disclosure is directed to a paper towel product that will capably separate from the paper towel roll as a full sheet, a half sheet or a quarter sheet. A method of making a paper towel with machine direction perforations is also disclosed.

Disclosed are apparatus and a method for converting a sheet into a continuous strip, wherein the apparatus comprises a cutting device with one or more cutting members, one or more drives, and a feeding device, wherein the apparatus is provided with one or more sensors for detecting the first longitudinal edge and the second longitudinal edge of the sheet and a control unit that is connected to the one or more drives, the feeding device, and the one or more sensors for controlling the movement of the one more cutting members relative to the sheet based on the detection to create a sequence of cuts to form interconnected sheet sections, wherein the control unit is arranged for variably controlling the strip width.

A stress tearable tape includes an elongated film and a hand tearing arrangement. The film has a non-adhesive surface and an opposed adhesive surface, and defines a longitudinal direction and a transverse direction. The hand tearing arrangement includes a plurality of pinholes formed along the longitudinal direction of the film. With the combination application of internal force, shear tension, compression tension, pinhole arrangement, and material's biaxial structure, and users' habit together, each of the pinholes enables the film being torn by hand with a force starting at one of the pinholes, such that the film is hand tearable at any section in the transverse direction thereof.

A sheet processing apparatus includes a blade having a plurality of teeth aligned in a row, a mover to move in a direction in which the plurality of teeth is aligned and form a perforation in a sheet sandwiched by the blade and the mover, and a pressure device to press the mover toward the blade.

The present disclosure is directed to a paper towel product that will capably separate from the paper towel roll as a full sheet, a half sheet or a quarter sheet. A method of making a paper towel with machine direction perforations is also disclosed.

A medium drying device includes a heat roller pair that dries a medium recorded and transported by a line head, and a perforation portion that forms a plurality of holes on an area including a recorded area of the medium. The perforation portion includes a plurality of piercing portions configured to pierce the medium, and the piercing portions are provided on an outer peripheral surface of a drying driving roller of the heat roller pair.

A packaging container includes an expandable plastic body having a front wall and a back wall, and a top, a bottom, and sides. Each side of the body has a gusset portion extending along a length thereof. Each gusset portion has gusset segments and a pair of adjacent gusset segments are joined along a common fold line. Each gusset segment has an inner surface and an outer surface. At least one of the gusset segments has an embossed section. The embossed section has a plurality of mounds protruding from one of the inner and outer surfaces and a plurality of depressions corresponding to the mounds within the other of said inner and outer surfaces. A roll for forming a packaging container, and method, are also disclosed.

The device assists in rapid caulking of seams between adjacent material; a tape is provided in rolls. The tape has a pair of parallel perforated lines running lengthwise along the center of the tape; and the tape having a pressure-sensitive adhesive coating on a bottom surface of said tape, the pressure-sensitive adhesive coating located between said perforated line and an exterior perimeter of said tape such that said tape is thereby comprised of three sections: a first adhesive section, a non-adhesive section and a second adhesive section, with the non-adhesive section defined by the perforated lines. The tape has an outwardly facing release coating such that the adhesive will releasably engage the top surface of the tape for manual separation of the tape when rolled upon itself. A crease is formed along the center of the tape to facilitate positioning of the tape in a wall corner. The tape also has a perforated removable center to be removed before caulking is applied.
