A method for producing a package comprising a formed part having at least one product cavity, and a lidding film covering the at least one product cavity, comprises the steps of: (a) defining a seam; (b) dividing the seam into a plurality of sections; (c) determining a pull-off force for pulling the lidding film from the formed part at least for a first section; and (d) sealing the lidding film to the formed part by means of a sealing device, wherein at least one first sealing temperature is selected for the first section based on the pull-off force determined according to step (c).

A method for producing and inspecting a package comprising at least one product cavity of a formed part sealed by a lidding film comprises the steps of: (a) sealing the lidding film to the formed part along a seam by means of a sealing device, which comprises a sealing contour with a plurality of segments; (b) detecting, by means of the sealing device, a parameter characteristic of the sealing quality of the seam in each segment; and (c) detecting a problem with the sealing according to step (a) based on the parameter detected according to step (b) in each segment.

A vacuum sealer includes: a housing comprising a vacuum chamber therein; a vacuum pump in fluid communication with the vacuum chamber; a sealing mechanism adjacent a periphery of the vacuum chamber; a valve positioned and configured to releasably seal the vacuum chamber, the valve movable between a first position, in which the valve forms a seal with the sealing chamber, and a second position, in which the valve does not form a seal with the sealing chamber; and a controller operatively connected with the vacuum pump, the sealing mechanism, and the valve. The controller is configured to move the valve from the first position to the second position during sealing.

A method of assembling a member and a cap of a vane using a tool which allows the application of a pressing force of the cap against the member during a step of polymerisation by heating a resin for bonding these components. To this end, the tool includes an inflatable bladder and a pocket which surrounds the bladder and the vane so that the inflated bladder applies the pressing force. The heating can be carried out by resistors which are mounted in the bladder and/or using a device for supplying external heat.

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 method for producing a package which has a formed part with a product cavity, and a lidding film covering the product cavity. According to the method, a seam is defined, the seam is divided into sections, a pull-off force for pulling the lidding film from the formed part at least for a first section is determined, and the lidding film is sealed to the formed part. The sealing temperature for the first section is selected based on the pull-off force.

The present invention provides an apparatus for producing and putting on gloves capable of producing gloves that fit an individual hand shape and also putting the glove on the hands, and a method for producing and putting on gloves. The apparatus [1] for producing and putting on gloves comprises welding and cutting means which welds and cuts a first elastic film and a second elastic film at a position on the outer side of a contour of a user's hand in a state in which the user's hand is sandwiched between the first elastic film and the second elastic film.
