Methods and apparatus for fabricating adhesive bonded joints while minimizing the voids and/or porosity found in the cured bondline. In accordance with various embodiments, the apparatus comprises an evacuation chamber combined with a pressure inducing device to produce bonded joints that are both void free and thoroughly compacted. The surfaces to be bonded are continuously evacuated throughout the bonding process (pre-mating, mating, debulking and cure). Continuous evacuation is provided via standard vacuum, while the induced pressure can be pneumatically or mechanically provided.

The invention comprising an appliance for vacuum sealing a bag member. The appliance has a housing including a front wall, a rear wall, and two side walls. The front wall includes an opening for receiving an open top portion of the bag member, where the bag member can then be received within a drip tray placed within a cavity located within the housing, where vacuum pressure may be applied. The drip try includes a barrier member that extends upwardly at a rear portion to redirect the open top portion of the bag member into the drip tray when the bag member has been inserted into the opening. The cavity also includes a heating bar used to apply a seal to the open top portion of the bag member. The front wall of the housing is angled between 15 and 45 relative to a surface on which the appliance rests.

A food storage appliance is provided including a housing, a lid pivotally attached to the housing movable between an open and closed position, an elongated heat sealing element, an elongated resilient bumper mounted on an underside of the lid with a plurality of elastic members which bias the bumper into an extended position when the lid is open, and when the lid is moved to the closed position the bumper sandwiches a portion of a food storage container to be sealed against the heat sealing element while the elastic members allow the bumper to adjust to maintain even pressure on the food storage container along the elongated heat sealing element.

An adjustable sealing apparatus and corresponding method of use is disclosed. The sealing apparatus has a variable range of motion programmed to accommodate multiple types of sealing motion, including the reciprocal motion and rotary motion. The proposed design uses two sealing jaw units with each sealing jaw unit located on opposing sides of a continuous layered film. Each sealing jaw unit has a sealing jaw coupled to a distal end of extendable linkages. The sealing jaws are extendable to allow the sealing surfaces to engage one another at a plurality of sealing locations along a plurality of sealing paths. Moreover a control unit is communicatively coupled to each of the sealing jaw units and controls movement of the sealing jaw units to engage one another at one or more of the plurality of sealing locations which enables sealing of the film to produce bags.

An apparatus for securing the tail end of a spirally wound roll of nonwoven, polymer-based material to the roll to preclude unintended unwinding of the roll, the apparatus comprising a winding assembly for forming about a winding axis a spirally wound roll with a tail end, a fixture for a roll tacking assembly with an ultrasonic tool oscillating on an oscillating axis, and a fixture for moving the tool into momentary tangential contact with an outermost winding layer of the roll in a manner that orients the oscillating axis orthogonally to the winding axis. The apparatus implements a method of locating the tail end of the spirally wound roll and orienting the tail end in relation to the securing tool.

An overwrap envelope (7) containing a filter bag (1) for infusion products comprises a sheet (2) of overwrapping material folded into a U shape along its transversal axis (X) around the filter bag (1). The overwrap envelope (7) has two longitudinal sides (3, 4) and one transversal side (5) sealed by at least two sealing lines (6) which are uninterrupted along the longitudinal sides (3, 4) and along the transversal side (5). Each scaling line (6) is defined by two longitudinal stretches and one transversal stretch which are joined to obtain an uninterrupted shape and which form an uninterrupted perimeter seal.

In order, in the case of a strapping apparatus for strapping articles with a strapping band, having a base plate which is provided for arranging on an article, having a tensioning device with which a band tension can be applied to the strapping band, the tensioning device being provided for this purpose with an actuable tensioning tool which can be brought into and out of contact with the band, having a sealing device with which, by contact with the band, two band layers can be permanently connected to each other by forming a seal between the two band layers, being provided with a clamping device which has at least one clamp with two interacting clamping elements for clamping the band between the clamping elements, and being provided with at least one actuating element with which a magnitude of a tensioning force which can be applied to the strapping band or a magnitude which is dependent on the tensioning force can be set, to improve the strength of friction-welded band strapping seals produced by the strapping apparatus, it is proposed that a cooling time period for the seal, during which the strapping apparatus does not release the strapping band after the end of a welding time, is variable depending on the variably adjustable tensioning force or a magnitude which is dependent thereon.

The techniques described herein relate to ultrasonic welding and related techniques for luggage. In some embodiments, a method of manufacturing a luggage component is provided that includes orienting a first component adjacent to a second component, wherein a first surface of the first component adjacent a second surface of the second component comprises a flat portion with one or more protrusions extending from the flat portion, and applying, via a horn sized to receive the first component, an ultrasonic vibration to melt the one or more protrusions to ultrasonically weld the first component to the second component.

The present invention relates to a device and a method for manufacturing a bag received in an envelope and containing a brewable material with a bag manufacturing means which is configured to manufacture a bag containing brewable material, and with a sealing station with a sealing jaw element and a counter-jaw element which act on the envelope from opposite sides to seal in the bag. The device is further developed for a reliable and safe manufacture of the packing unit consisting of a bag and an envelope by the sealing jaw element being fixed to a sealing jaw swivel arm at which a sealing jaw connecting rod is applied, and the counter-jaw element being fixed to a counter-jaw swivel arm at which a counter-jaw connecting rod is applied, and by the sealing jaw connecting rod and the counter-jaw connecting rod being each eccentrically connected to a common drive shaft of a servomotor. In the method according to the invention, the contact force between the sealing jaw element and the counter-jaw element is controlled via the torque of the servomotor actuating the sealing jaw element and/or the counter-jaw element.
