The present invention relates to an apparatus and a method of folding a pouch case of a battery cell, and more particularly, to an apparatus and a method of folding a pouch case of a battery cell capable of preventing a meandering in a folding process and reducing non-uniformity of a folding amount by forming a pre-folding line on a pouch wing and folding the pouch wing on the basis of the pre-folding line.

A bag-making and packaging machine forms a sheet-like film into a tubular shape and transversely seals the film to manufacture bags containing articles. The bag-making and packaging machine includes a transverse sealing mechanism and a control unit. The transverse sealing mechanism pinches and transversely seals the tubular film that has been formed into a tubular shape to form a transverse seal portion. The control unit determines whether or not there is jamming in the transverse seal portion and, in a case where it has determined that there is jamming, switches between a first bag-making process to continue bag-making operation and a second bag-making process to stop bag-making operation based on a jamming state.

A welding apparatus is suitable for welding polymeric materials, and particularly but not exclusively those that may be thin or brittle. A welding apparatus is provided for welding polymeric materials along a weld zone of the polymeric material. The welding apparatus has a carrier for supplying heat to the weld zone to cause melting of the polymeric material, wherein the heating element is arranged to reciprocate relative to the carrier between a retracted and an extended configuration, such that as the element moves from the retracted to the extended configuration the heating element melts and penetrates the surface of the polymeric material. The carrier also has a trailing contact surface trailing the heating element along the weld zone arranged to constrain molten polymeric material in the weld zone. The heating element is also arranged to reciprocate relative to the trailing contact surface.

A film or packaging member for forming a package comprising at least one body and at least one outer adhesive layer, wherein the body and adhesive layer are made of a polyolefin-based plastic, wherein at least the adhesive layer is fusible to be weld to a target surface, and wherein at least the adhesive layer comprises particles that absorb radiation to heat at least a portion of the packaging member.

A method for manufacturing a laminated molded body includes a cutting-out step for cutting out a cushion layer to form a cut-out part; a base material laminating step for forming a first laminated body; an insulating material placing step of attaching an insulating material to the cut-out part; a first thermocompression bonding step for bonding the first laminated body by thermocompression; a removing step for removing the cut-out part to form an opening; a skin laminating step for forming a second laminated body; and a second thermocompression bonding step for bonding the skin at the opening part to the lower layer material by bonding the second laminated body by thermocompression, the lower layer material being arranged below the cushion layer having the opening part.

A vacuum packaging device includes a hexahedral housing having a space inside; a grip unit in which a pair of grip bars selectively come into surface contact with each other above a front side of the housing; a suction nozzle unit which moves forward and backward along a guide inside an inner space of the housing; a pair of heat-pressing members which are respectively provided in the pair of grip bars; and lifting and lowering means for lifting and lowering an upper grip bar of the pair of grip bars and an upper heat-pressing member of the pair of the heat-pressing members inside the inner space of the housing by a process step.

A barn curtain having a transparent panel and a non-transparent panel is prepared by a welding machine. The welding machine has an inner heater assembly including a first roller wheel, an inner plate assembly having a lower inner plate and an upper inner plate spaced apart from the lower inner plate in a vertical direction, and a heater, and a first roller assembly including a second roller wheel aligned with the first roller wheel. A side of a transparent panel is fed through the lower inner plate and a side of a non-transparent panel is fed through the upper inner plate. The plates are heated with the heater to partially melt the side of the transparent panel and the side of the non-transparent panel. The side of the transparent panel and the side of the non-transparent panel are pressed between the roller wheels and joined.
