A method for manufacturing a fuel cell assembly includes: arranging an end face of a gas diffusion layer on a placement jig in a state abutting an end face of a resin frame; melting a part of the frame member and causing to penetrate into the gas diffusion layer by pressurizing the projecting part by way of a heat-transfer member, and heating the projecting part via the heat-transfer member by abutting a heating member against of the heat-transfer member; and solidifying the part of the resin frame having penetrated into the gas diffusion layer, in which an abutting position of the heating member relative to the heat transfer member is set in the melting step so that a central axis of the heating member is positioned more to a side of the gas diffusion layer than the central axis of the projecting part.

The invention relates to a method for producing tubular bags made from plastic film or from composite film having a plastic layer on the bag content side, having a self-cutting plastic closure attached to the tubular bag, consisting of a spout part having a fastening flange, a cutting body, which is movably guided in the spout part, and a screw cover having means for activating the cutting body. The film material (5) is supplied from a supply roll to a bag manufacturing machine and the plastic closure is sealed onto the film material in a spout region of a tubular bag. According to the invention, the film material (5) is thinned on the inside of the bag in a ring-shaped region, which is intended for cutting by the cutting body, by means of a thermal embossing process. The plastic closure is then positioned and sealed onto the film material such that the cutting organ embedded in the spout part can become effective in the thinned, ring-shaped region upon use thereof.

An inductor for induction welding of a packaging material having at least one layer of metal foil is disclosed. The inductor comprises a welding surface configured to be arranged opposite the packaging material for heating thereof, and at least one spacing element arranged to protrude from the welding surface in a first direction towards the packaging material, when the packaging material is arranged opposite the welding surface, whereupon the least one spacing element separates the packaging material from the welding surface by an off-set distance. A sealing machine for sealing packaging material and a method of welding a packaging material is also disclosed.

A sterile connection device includes first and second carriages. The first carriage defines a first portion of a proximal slot and a first portion of a distal slot, while the second carriage defines second portions of the proximal and distal slots. A controller executes a sterile connection procedure in which a solid cutting blade is heated, followed by the heated blade being moved to a cutting position to cut sealed proximal and distal tubes received by the slots. The second carriage moves proximally or distally with respect to the first carriage so as to align the cut ends of the tubes. The heated blade then moves out of the cutting position, followed by the first carriage moving toward the second carriage so as to press the cut ends of the tubes into contact with each other so as to sterilely connect the cut ends and define a joined tube.

A vibration welding device includes a base plate, a vibrating body, and a plurality of position adjusting jigs. The vibrating body is capable of vibrating while holding an interior part which is an object to be welded. The base plate is disposed below the vibrating body. The base plate holds an instrument panel which is an object to be welded. The position adjusting jigs are connected to the vibrating body so as to be adjustable in position. The plurality of position adjusting jigs are disposed independently of each other.

A heating unit is described and illustrated including at least two heating devices for at least partially heating with hot air end areas of package sleeves to be sealed, wherein the heating unit has an air supply device for supplying air to be heated to the heating devices, wherein the heating devices each have a heating element for producing hot air and a nozzle unit for blowing hot air produced in the heating device against the end area of the package sleeve. In order to be able to increase the leak tightness of the sealed end areas of the package sleeves without having to accept an excessive outlay and effort in terms of the equipment and/or in terms of the method for this, it has been proposed that the heating devices are each separately connected to the air supply device by means of at least one holder and are each separately held on the air supply device by means of the at least one holder.

A device for welding thermoplastic tubes to a welding method, and to a welding knife. The device is provided for welding thermoplastic tubes, wherein the tubes are placed into tube holders and squeezed with the aid of tube clamps. A welding knife is moved between the first and the second tube holder and severs the tubes in the process. Cut ends and residual ends are thereby produced. The cut ends are aligned with one another by a relative movement of one tube holder with respect to the other tube holder and, by a horizontal movement of the two tube holders, are welded simultaneously to form continuous tubes.

A head seal device of a bag making apparatus includes a pair of seal units configured to face each other in a facing direction. Each of the seal units includes a heat seal member and a heater. The heat seal device includes an adjustment unit configured to move the first seal unit in a width direction of continuous sheet panels, and to move the second seal unit in the width direction of the sheet panels in accordance with movement of the first seal unit in the width direction.

A system and method for controlling the speed of both a continuous web and a bonding apparatus is provided in order to effectuate stronger bonds in the web. The bonding system includes a velocity changing device for increasing and decreasing a velocity of the web in a machine direction, an anvil and a corresponding ultrasonic horn that interact to form ultrasonic bonds on the web, and an anvil actuator configured to control a movement of the anvil. A control system is also included in the bonding system for controlling operation of the anvil actuator the velocity changing device, with the control system programmed to decrease a moving velocity of the web from a feed velocity to a bonding velocity as the web passes between the anvil and the ultrasonic horn and control movement of the anvil to synchronize the movement of the anvil with the moving velocity of the web.

The seal plate assembly of this invention includes a base plate, an insulator pad positioned on the base plate, an electric heater pad positioned on the insulator pad and a pair of seal plates positioned on the electric heater pad, all of which have registering vacuum openings formed therein. The base plate, insulator pad, heater pad and seal plates are bolted together. The seal plates have spaced-apart cavities formed therein. A support plate is positioned in each of the cavities with each of the support plates having a length and width which is less than the length and width of the respective cavity to create a vacuum space at the perimeter of the support plates. The support plates are spaced above the bottom of the cavities.
