摘要:
Device for manufacturing cushions filled with a medium from synthetic pre-processed tubular foil (2). Flexible pre-processed tubular foil is supplied to the device by a supply device in a supply direction. The pre-processed tubular foil is supplied in flat condition. The pre-processed tubular foil has a first (6) and a second (7) longitudinal edge opposite each other. An introduction means (9) for introducing a medium is provided. A cutting means (8) is present for making a cut in the pre-processed tubular foil only and at least near the first longitudinal edge of the foil. Sealings means (11) are provided for sealing the pre-processed tubular foil parallel and between the introduction means and the second longitudinal edge, for sealing off the cut. Series of cushions or a cushion filled with a medium according to the invention have a second closed off longitudinal edge, a first cut-through longitudinal edge formed by two ends situated opposite it, and a longitudinal seal situated between the first and the second longitudinal edge.
摘要:
Machine and method for manufacturing pneumatically filled packing cushions. A length of flattened flexible tubing is fed through a machine and perforated to form a row of openings across the tubing. Gas is injected into the tubing through the openings, and the tubing is then sealed together across the openings form a chamber in which the gas is confined.
摘要:
There is disclosed a method of packaging loose fill packing material in bags for use as cushions in shipping cartons, wherein a length of flexible plastic tubing is gathered to form a coil from which successive sections can be pulled; the coil is positioned about the outlet of a packing material dispenser; a first section of the tubing is pulled from the coil, closed at its lower end, filled with packing material. A second section of the tubing is pulled from the coil; the tube is drawn together between the two sections, the closed ends of which one then secured; and screwing the tubing between the two sections. The bag sealer and cutter has a guide for directing a portion of flexible tubing which has been gathered together along a predetermined path in a direction which is generally perpendicular to the axis of the tubing, a pair of tape applicators positioned side-by-side for simultaneously applying bands to the gathered together portion of the tubing as the tubing travels along the path, and a knife disposed in the path of the tubing after the applicators for cutting the tubing apart between the bands of tape.

An inflatable, conformable, cushioning, packaging product (11) comprises a plurality of individual inflatable strips (21) of multiple bubble cushioning structures. Each individual inflatable strip (21) has a plurality of bubble chambers (23) with each bubble chamber (23) interconnected to an adjacent bubble chamber (23) by an interconnecting passageways (25) which is smaller in size and internal volume than the bubble chambers (23), but which is sufficiently large to enable air volume and pressure in one inflated bubble chamber (23) to be transmitted to adjacent bubble chambers (23) for distributing a shock load on one bubble chamber (23) along the entire length of the individual inflatable strip (21) of interconnected bubble chambers (23). Each individual inflatable strip (21) is defined between two laterally extending spaced apart peripheral seal lines (43) which have an undulating configuration free of corner shapes which could concentrated stresses.
摘要:
An apparatus for inflating and sealing packing cushions utilizes a controller adapted for acquiring information from preconfigured film material and automatically setting one or more operation parameters suitable for inflating and sealing the film. The controller can avoid or limit the need for user input, thus simplifying use of the apparatus.
摘要:
An apparatus for inflating and sealing packing cushions has a drive mechanism for feeding a preconfigured film material to a sealing mechanism in a flattened state without wrinkles in the sealing region in which a longitudinal seal is formed. In one aspect, the drive mechanism comprises a pair of upper adjacent belts and a backing element, such as a lower belt. The sealing mechanism may be a rotary sealing wheel that contacts the film material between the upper adjacent belts.
