An anvil is provided in an ultrasonic sealing machine, in which vibration applying surfaces of a pair of horns and an abutment surface on an end face of the anvil cooperate with each other to bond a laminate. The abutment surface includes left and right welding surfaces which are disposed in the extending direction of the vibration applying surface and protrude toward the horns to face two vibration applying surfaces. The left and right welding surfaces each have an area per unit length in the extending direction, which continuously or step-wisely increases with an increase in distance from a center of the seal area, which is a region where the two vibration applying surfaces are adjacent to each other.

A flexible container incorporating flexible front and rear sheets with a perimeter seal in which at least one length or section of the perimeter seal can include a seal weld that has both a permanent seal section and a pressure absorbing seal section. The pressure absorbing seal section is configured to peel, fail, or split when the flexible container, filled with a solution or liquid, is dropped onto a hard surface to thereby absorb the impact of the drop. The flexible container can be provided with one or more dispensing and/or additive ports or without any port. The flexible container may include more than one compartments with a peelable seal separating two adjoining compartments of the flexible container.

A method and a device for heat sealing multiple plies of a laminate from which gable top packaging can be produced, wherein the laminate has a carrier layer made of electrically non-conductive material and a sealing layer made of thermoplastic material on at least one surface of the laminate. To heat seal multiple plies of a laminate in a high-frequency alternating electric field, the alternating electric field is generated by a first lead of an HF voltage supply in a first sub-region of the sealing region and is generated by a second lead of the HF voltage supply, differing from the first lead, in at least a second sub-region of the sealing region, so that a different heat distribution is obtained over the sub-regions of the sealing region.

A method for producing insulating profiles comprises manufacturing a profile body and a first functional element separately, and the profile body and the first functional element are supplied to an ultrasonic welding device, wherein the profile body and the functional element are connected to one another by a material bond by formation of a welded joint. The profile body and the functional element are brought together into a predetermined first cross-sectional geometry during formation of the welded joint and are thereafter guided in this cross-sectional geometry until the plastics material of the welded joint solidifies to such an extent that the profile body and the first functional element are fixed in the predetermined cross-sectional geometry.

There is provided an apparatus 1 that includes a pair of molds 10a and 10b that press together, heat, and weld an overlapping part of a plurality of film-like members, a pair of heater blocks 20a and 20b that respectively support the pair of molds; a plurality of first support blocks 37 that are connected via a plurality of rod-like members 50, which midway include parts that restrict transmission of heat, to one heater block 20a; a plurality of second support blocks 38 that are connected via the plurality of rod-like members to the other heater block 20b; and a driving mechanism 60 that changes, via the support blocks, a gap between the pair of molds to press together the film-like members. The plurality of first support blocks include at least one movable support block 39 including a mechanism 35 that moves in a first direction relative to the driving mechanism corresponding to thermal deformation in the first direction of the heater block to be supported, and the plurality of second support blocks include at least one movable support block 39.

Provided is a sealing apparatus of a pouch-type secondary battery, capable of preventing electrolyte leakage by constantly positioning a lead on a sealing groove so as to completely seal the secondary battery. A sealing apparatus according to the present disclosure is a sealing apparatus of a pouch-type secondary battery which seals a pouch case in which an electrode assembly is installed. The sealing apparatus includes upper and lower sealing blocks, wherein at least one sealing block of the upper and lower sealing blocks has a sealing groove having a slanted step portion which is formed at a position corresponding to the lead of the pouch-type secondary battery and a lead guide for seating the lead on the sealing groove is installed in front of the sealing block.

A wafer bonding apparatus includes a first bonding chuck to fix a first wafer on a first surface thereof, a second bonding chuck to fix a second wafer on a second surface thereof facing the first surface, a bonding initiation member at a center of the first bonding chuck to push the first wafer towards the second surface, and a membrane member including a protrusion protruding from a center portion of the second surface towards the first surface, and a planar portion defining the protrusion on an outer region surrounding the center portion.

A tube seal apparatus including a sealing iron having a tube sealing end, an insulating shroud having a tube clamping end, wherein the sealing iron is at least partially disposed within the insulating shroud. The apparatus further includes an anvil having a cutting detail and a non-stick membrane disposed between the anvil and the tube clamping end of the insulating shroud. The sealing iron and insulating shroud are configured to advance towards a tube to be sealed positioned between the non-stick membrane and the anvil. The tube clamping end is configured to clamp the tube through the non-stick membrane. The sealing iron is configured to advance towards the tube to melt and seal the tube against the cutting detail through the non-stick membrane.

The invention relates to a sealing tool (100) with a sealing surface (110) for sealing sheets (200) of metallized substrate, such as metallized paper or metallized plastic material, in cooperation with a sealing tool counterpart (190), which is arranged opposite to the sealing tool (too) with respect to the sheets (200) that are to be sealed. The sealing surface (no) comprises a plurality of sealing sections (111-115), which all face in the same sealing direction (SD) of the sealing tool (100), and has a sealing width extending transversely to the sealing direction (SD) of the sealing tool (100) from an outer sealing tool side (121) to an inner sealing tool side (122). The sealing sections (111-115) are arranged side by side in a stepwise manner so that, from the outer sealing tool side (121) to the inner sealing tool side (122), every sealing section (111-115) is offset from its neighbouring sealing section (111-115) in a direction opposite to the sealing direction (SD) of the sealing tool (100). The invention also relates to an apparatus (300) for sealing two sheets (200) of the metallized substrate with the sealing tool (100). Further, the invention relates to a packaging (400) for enclosing a substance and a method of producing such packaging (400).
