Thermoforming Apparatus Having Deformation Sensor and Method
A thermoforming apparatus is provided having a pair of coacting platens, a load bearing structural member, a force applicator, and a deformation sensor. The pair of coacting platens and respective dies are configured to mate on opposed surfaces of a heated sheet of thermoformable material to form articles. The load bearing structural member is configured to carry the coacting platens and the dies in complementary closed relationship about the sheet during an article forming operation. The force applicator is carried by the structural member and configured to impart a forming load between the pair of opposed dies and platens and across the structural member during a forming operation. The deformation sensor is configured to span a first location and a second location on the structural member to detect deformation indicative of separation between the dies resulting from deformation. A method is also provided.
METHOD FOR MANUFACTURING HOLLOW MOLDED ARTICLE AND APPARATUS FOR MOLDING HOLLOW MOLDED ARTICLE
While naturally suctioning air between a first thermoplastic resin sheet and a second thermoplastic resin sheet from a fluid passage formed in a first thermoplastic resin sheet, the first thermoplastic resin sheet is subjected to vacuum-molding by a first vacuum molding die, a first shaping section is formed in the first thermoplastic resin sheet by a molded section of the first vacuum molding die, the second thermoplastic resin sheet is subjected to vacuum-molding by a second vacuum molding die, a second shaping section is formed in the second thermoplastic resin sheet by the molded section of the second vacuum molding die, and a hollow section is defined between the first thermoplastic resin sheet and the second thermoplastic resin sheet by the first shaping section and the second shaping section.

METHOD FOR MANUFACTURING AN INJECTION DEVICE WITH A BYPASS CHANNEL AND TOOL FOR THIS PURPOSE
A tool and a method for manufacturing a bypass in an injection device are disclosed. The preforms of the injection device are inserted into a tool. A partial region of the cylindrical portion is heated by a heat source. The heated partial region of the cylindrical portion is plastically deformed with a male die part of the tool, so that the bypass channel is formed.

METHOD AND DEVICE FOR FORMING SHOE UPPER DECORATION
A method and a device for forming shoe upper decoration essentially include a machine, an upper mould and a lower mould. The upper and lower silica gel sheets are separated from the upper and lower heaters by a distance, which provides a suspended indirect heating mode to prevent the upper of the shoe from being deformed by the direct heating of the heat source, and to achieve the purpose of reducing the possibility of non-conforming products.
Method for making an apertured web
The present invention relates to a method for making an aperture web, comprising moving a micro-textured web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web. The present invention also relates to a method for making an aperture web, comprising forming microtextures on a web, and continuously moving the web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web.
Seal bar and heat sealing apparatus
A technique for accurately detecting a temperature of a sealing surface which is not affected by sealing conditions or the like is provided. A seal bar (1) is a rod-shaped seal bar having a sealing surface (11a) and includes a heater (13) and a temperature sensor (14).
