A paper separator provided with an adhesive tape cutting assembly includes a housing structure and an adhesive tape cutting assembly, where a housing has an open first end and an open second end, the first end and the second end are axially through and forms a cavity capable of accommodating a paper roll inside the housing; a cavity opening is formed in an outer wall of the housing and is axially formed from the first end to the second end; and the adhesive tape cutting assembly is fixedly mounted on the outer wall of the housing and is configured to be sleeved with an adhesive tape roll and cut an adhesive tape.

An intermittent composite strip, a preparation method therefor, a transfer strip, a preparation device and a preparation method therefor. The preparation method for the intermittent composite strip includes the following steps: acquiring the transfer strip, where the transfer strip includes a load strip and a first composite material strip, and the first composite strip is intermittently arranged on the load strip; acquiring a second composite material strip, where a bonding force between the second composite material strip and the first composite material strip is greater than that between the first composite material strip and the load strip under a same pressure; and performing pressure bonding on a side of the transfer strip including the first composite material strip with the second composite material strip to obtain the intermittent composite strip.

Embodiments of the present application disclose an integrated paper and adhesive tape cutting device, including a housing, where the housing includes a paper cutting housing and a paper separating housing; a component for pulling out paper from a paper roll inside a paper separating component for cutting is arranged below the paper cutting housing; and a cutting device is arranged on an outer wall of the housing to cut an adhesive tape.

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 method for splitting a semi-finished product includes placement of the semi-finished product on a splitting template, and the splitting template includes at least one elevation. The method includes fixation of the semi-finished product on the splitting template, in which an area of the semi-finished product is arranged on the elevation. The method includes splitting of the semi-finished product, in which material is removed from the semi-finished product during splitting. The material removal in the area that is arranged on the elevation is greater than in an area that is not arranged on the elevation.
