Provided is a composite material bonding apparatus that can reduce a cycle time when composite material members are bonded to each other. The composite material bonding apparatus includes a sheet-heater moving device that places a graphite heater at an insertion position between a first bonded surface of a first composite material member and a second bonded surface of a second composite material member such that the graphite heater is parallel to the first bonded surface and the second bonded surface facing the first bonded surface, and retracts the graphite heater to a retraction position from the insertion position. The first bonded surface and the second bonded surface are heated at the insertion position by the graphite heater, and then the graphite heater is moved to the retraction position by the sheet-heater moving device.

A machine includes an inflation arrangement, a sealing arrangement, and a tensioning device. The inflation arrangement provides air at a first pressure to inflate a first web of a first type of inflatable material, provides air at a second pressure to inflate a second web of a second type of inflatable material, receives the first and second webs, and aligns the first and second webs on the machine. The first pressure is different from the second pressure. The sealing arrangement seals the first and second types of inflatable material. The tensioning device provides a first tensioning force to the first web as the first web moves between the inflation and sealing arrangements and provides a second tensioning force to the second web as the second web moves between the inflation and sealing arrangements. The first tensioning force is different from the second tensioning force.

Bag-sealing apparatus is provided for heat-sealing a bag. The apparatus has a heater arrangement operable to apply heat to heat-seal an open end of the bag. A bag detector detects the location of the bag relative to the heater arrangement. The heater arrangement is formed of plural heater portions. The heater arrangement is operable such that only the or each heater portion that overlies the bag as detected by the bag detector is caused to operate to apply heat to the bag.

A film-closure apparatus is provided which is suitable for closing plastic film material using heat. The apparatus comprises a guide path along which at least part of a plastics film material can pass; a drive means for moving the film material along the guide path; and a printed circuit board comprising a circuit substrate having first and second major board surfaces and a perimeter edge surface, and an electrically conductive heating element which is provided on the circuit substrate along at least part of the perimeter edge surface. The electrically conductive heating element is positionable on the guide path to apply heat to the film material thereon.

An apparatus for vacuumizing and sealing a package includes a plurality of platens and vacuum chambers, each chamber adapted to mate with a dedicated one of the platens; a conveying system for conveying the platens and chambers along a generally angular path having a single axis of rotation; an automated loading assembly having a linear component and configured to load a package onto each of the platens; an automated unloading assembly having a linear portion and configured to unload a vacuumized, sealed package from each loaded platen onto an outfeed conveyor; and a vacuumizing/sealing system configured to cause relative movement of each chamber/platen pair, along a portion of the angular path, to form therebetween an air-tight enclosure accommodating the package and effect vacuumization and sealing of the package.

A protective packaging formation device is disclosed herein. The device includes an inflation assembly that directs fluid between first and second overlapping plies of a web material. The device also includes a sealing mechanism. The sealing mechanism includes a heating zone and a cooling zone. The sealing mechanism also includes a heating element that extends along both the heating zone and the cooling zone, with the heating element having a first profile in the heating zone and a second profile in the cooling zone.

Disclosed is an apparatus for manufacturing an internal tension member of an inflatable product, the apparatus comprising: a support frame; a base plate arranged to pass through the inside of the support frame; a base strip conveying device comprising two inner base strip reels, two outer base strip reels and a traction wheel which are used for continuously supplying base strips, the traction wheel pulling four base strips to continuously move; a wire winding device comprising a rotation device arranged around the base plate and wire winding guide shafts symmetrically arranged on two sides of the base plate, the rotation device winding a wire on two inner base strips in a rotating manner; and a welding device positioned between the wire winding device and the traction wheel, the welding device respectively welding the two inner base strips to the corresponding two outer base strips. Further disclosed are a method for manufacturing an internal tension member of an inflatable product, an internal tension member of an inflatable product, and an inflatable product.

The invention is a device for welding two overlapping film sections situated on one side of a goods stack. The device includes a welding bar with a welding surface oriented in the direction of the film sections to be welded. The spacing between the welding bar and the film sections is reducible. The welding surface is elastically deformable into a concave course and/or to a convex course between its two ends. At least one displacing device adjusts the course of the welding surface to a concave and/or to a convex course. The displacing device displaces welding bar. A control unit of the welding bar individually controllable, such that the curvature of the welding bar is adjustable to the contour of the side of the goods stack in the region of the film sections to be welded with one another for the subsequent welding of the overlapping film sections.
