The invention proposes a cutting device for cutting a material, comprising a cutting wire (3) having two ends, each end being connected to a winding drum (1a, 1b), the wire (3) being tensioned, the wire (3) being conductive and having a voltage applied to it in order to heat. This cutting device is characterized in that the wire (3) is unwinding at the moment of cutting, with winding around a first drum (1a) taking place simultaneously to unwinding from a second drum (1b), the device having a dry cutting zone (2) in which is located an unwinding section of wire (3) able to cut the material coming into contact with it, the two drums (1a, 1b) being driven in rotation by two different motors (4).

The hotwire cutting machine (700) comprises a plurality of heated wires (701), springs (702, 702a), and grooved rods (703, 703a, and 1203) supported on end bearings (402, 403). The grooved rods (703, 703a, and 1203) are coupled to a motor (504) for rotating the grooved rods (703, 703a, and 1203) in the direction of wire movement due to thermal expansion. The wires are oscillated along their length by the to-and-fro rotation of a splined shaft (704, 1204). Existing solutions oscillate the entire heavy frame, resulting in vibrations and requiring heavy motors and drives. In contrast, the proposed hotwire cutting machine (700) minimizes the oscillating mass and allows for automatic adjustment of inter-wire distance/pitch. The composite cutting wire section includes a first wire (1209) with high mechanical strength and low electrical resistance, joined by manual twisting or welding with a second wire (1201), typically Nichrome, to withstand repeated bending cycles.

The invention relates to a method for measuring a thickness (d) of a film (90) or sheet (90), wherein the film (90) or sheet (90) is cut as an article of manufacture made from a block material intended as a source material (80), in particular, from a block of foam. The source material has a source-material length (81, 85) extending in the longitudinal direction (x; x), a source-material width extending in the latitudinal direction (y) (82, 86) and a source-material height extending in the vertical direction (z) (83, 87). In this method, the source material is conveyed along the longitudinal direction (x; x) to a cutting unit (50) in order to cut the source material. The cutting unit (50) cuts the film (90) or sheet (90) out of the source material along the longitudinal direction (x; x). In addition, in order to determine the thickness (d) of the film (90) or sheet (90), the thickness (d) along the vertical direction (z) is determined. Furthermore, the invention relates to a system for manufacturing a film (90) or sheet (90), as well as a method for operating such a system.

A method and system for fabricating a disposable free-standing surgical pillow is described and includes employing a contour cutting machine to form lateral notches, profile portions and base portions in an intermediate workpiece, wherein the profile portions include opposed side support portions and a medial notch. A die cut press executes through-cuts and partial cuts to form medial cutout portions. At least one lateral cut and at least one longitudinal cut are executed to separate the intermediate workpiece into a plurality of individual workpieces in the form of the surgical pillows.

In order to provide a manufacturing method of an elongated foam sheet capable of manufacturing the elongated foam sheet with highly-precise thickness without being limited by the material and thickness of foam material, a method of manufacturing an elongated foam sheet includes performing a slice process in which a foam sheet is created by slicing a foam block and a sheet pasting process in which a large number of foam sheets are arranged and pasted onto one side of an elongated base material sheet to manufacture the elongated foam sheet where the large number of foam sheets are lined up in a longitudinal direction of the base material sheet.

A shipping container including a multilayer composite including a core layer including an assembly and a first cover layer provided on the core layer, wherein the first cover layer includes a first composition having a density of at least 0.903 g/cm.sup.3 and including polypropylene and optionally reinforcement fibers such as glass fibers wherein the assembly includes a plurality of elongated foamed elements that are arranged next to one another in one plane and bonded to one another at abutting side faces thereof, wherein the elongated foamed elements have been made by cutting at least one foamed sheet having a top surface and a bottom surface, the at least one foamed sheet having been prepared by a foamed extrusion process and the foamed sheet includes a polymer composition including polypropylene, wherein the cutting is perpendicular to the top surface and the bottom surface of the at least one foamed sheet.

The present disclosure provides a stretchable foam, furniture, and a cutting tool. The stretchable foam is provided with a slit group, and the slit group includes two rows of slits. Each row of slits includes multiple cutting units arranged at intervals. Each cutting unit includes a first straight edge and a second straight edge connected to each other, and the first straight edge and the second straight edge form an opening. The openings of the multiple cutting units in the first row of slits and the multiple cutting units in the second row of slits are arranged in opposite directions and are staggered in sequence. The adjacent first straight edge and second straight edge of two adjacent cutting units in the first row of slits are located within the opening of the same cutting unit in the second row of slits.
