A sheet bonding device includes a pressurization mold which is constituted of an upper mold and a lower mold and performs sealing through heating by sandwiching a sealing target portion of a bag main body and a sealing target portion of a gas barrier function sheet with pressurization surfaces; a plurality of support pins which are provided in the lower mold so as to be retractable and position the gas barrier function sheet with respect to one surface of the bag main body by penetrating the sealing target portions of the bag main body and the gas barrier function sheet; and gas spray means for making the gas barrier function sheet float by spraying inert gas to an area-enlarged portion, which does not overlap the bag main body, of the gas barrier function sheet supported by the support pins.

A microfluidic device comprises a first substrate (102) made of a first polymer material and a second substrate (104) made of a second polymer material, the first (102) and second (104) substrates having respective bonding surfaces (23, 41), at least one of the bonding surfaces (41) having channel formations (14) so that, when the bonding surfaces (23, 41) are bonded by surface deformation to one another, the bonded first and second substrates (102, 104) and the channel formations (14) form at least part of a microfluidic channel network comprising a plurality of microfluidic channels, wherein one or more indicator pits (11), separate to the channel formations (14) defining the microfluidic channel network, are formed in at least one of the bonding surfaces (23, 41), so that surface deformation caused by the bonding process causes a change of configuration of the one or more indicator pits (11).

Systems, apparatuses, and methods to seal a container are provided. An apparatus for securing a film to a container includes a body portion to house film and a sealing portion. The sealing portion includes a sealing volume for receiving a portion of the container, at least one heating element positioned within the sealing volume, and a sensor configured to sense when the portion of the container is at least partially within the sealing volume. A controller is configured to receive a sensor input from a sensor indicating that the portion of the container is at least partially within the sealing volume, and activate the at least one heating element based on the sensor input.

Process for manufacturing inflatable bodies capable of assuming a desired complexly curved shape comprising two, around their circumference hermetically bonded opposing membranes (3, 4), which are internally linked by a plurality of link tapes (1), which tapes are bonded at an exact length and inclination angle at an exactly determined position. By numerical instructions, a continuous tape is fed and bonded alternately on the insides of the membranes by means of a roboticized tape positioning head, creating bond lines (2) between the tape and a membrane. Any fold occurring through local inclination, or planar angle variation of the tape relative to a membrane is kept between two bond lines on a membrane (3,4). A roboticized tape positioning and bonding head inside, and a bond activation head outside of a membrane can position relative to a membrane (3,4) by means of printed positioning marks, optical and proximity sensors to create the bond lines (2).

A method for welding a ball onto a first component includes the following steps: providing a first component; creating a physical mark in or on the first component; positioning the ball in the place where the physical mark has been created; and welding the ball in a non-contacting manner to the first component using a laser welding device that is positioned at a distance from the first component and the ball.

Installation fittings for use with induction weldable pipe connectors for assembling multi-layer pipe fluid distribution systems. Induction welding pipe connectors including a major central pipe connector section and a minor lateral pipe connector section pair having reduced thickness relative to the major central pipe connector section. Induction welding pipe connectors with 5 integral solder flow barrier for assembling fluid distribution systems. Electromagnetic induction coil reverse action pliers for use with induction weldable pipe connectors for assembling fluid distribution systems.

An apparatus may include a film support roller supporting a film roll and a housing that may include a sealing portion having an aperture sized to receive a top portion of a container. The housing may define a film path leading from the film roll to the sealing portion. A guide support assembly may have a ramp and at least one guide truss positioned along the film path. The ramp and the guide truss may guide the film across the aperture within the sealing portion, covering the aperture. The motor may advance the film along the film path. The heating element may emanate energy. The controller may cause the motor to advance the film onto the ramp and cause the heating element to emanate energy to cause the film to seal the top portion of the container.

An apparatus includes a body portion configured to house a film roll that has a length of film and a sealing portion configured to receive at least a top portion of a container. The sealing portion includes an aperture sized to receive the top portion of the container therethrough. The body portion defines a film path leading from the film roll to the sealing portion. The apparatus includes a nip defined by a drive roller and a pinch roller. The nip is positioned along the film path and configured to receive a portion of the film therethrough. The pinch roller is adjustable in relation to the drive roller. The apparatus includes a motor configured to operate the drive roller, a heating element, and a controller. The controller is configured to cause the motor to operate and to cause the heating element to activate.
