摘要:
An apparatus for manufacturing a cutter and attaching the cutter to a carton including a vertically movable upper mold provided with an upper blade having an edge and a suction device for sucking and holding a severed nonmetallic cutter, a fixed lower mold provided with a lower blade having an edge where the lower mold engages with the upper mold, a feeding device for intermittently feeding a sheet on the lower mold, and a conveying device for conveying and setting sequentially the cartons one-by-one to a bottom dead center of the upper mold. In the alternative, the lower mold can be vertically movable and include the section device while the upper mold is fixed.

A method of attaching a cutter to a carton includes the steps of feeding intermittently a nonmetallic sheet by a feeding device toward upper and lower molds, one of which is vertically movable, punching the nonmetallic sheet by the molds to form the cutter, conveying and setting cartons one by one by a conveying device, sucking and holding the cutter on the movable mold, and pressing the cutter to the carton which is adhered thereto by an adhesive paste applied to the cutter. The nonmetallic sheet has an adhesive paste on one side and a removable sheet on the paste which is peeled away prior to punching.

This invention provides an embossed release paper for synthetic leather production, which has embossability, heat resistance and durability and, at the same time, has excellent separability from a two-pack curing type PU adhesive and can be used in all of synthetic leathers such as PU, PVC, and semisynthetic leathers, and a process for producing the same. The embossed release paper for synthetic leather production comprises at least paper as a support and an ionizing radiation cured film provided on the paper. The upper part of the cured film has been embossed. The ionizing radiation cured film has been formed by applying an ionizing radiation to a coating liquid having a specific composition to cure the coating liquid.
