The disclosure relates to a heating device capable of uniform sealing, uniformly applying heat at a constant temperature to the entire sealing portion of the to-be-sealed object to heat and seal the entire sealing portion at a constant temperature, thereby providing the uniform sealing thickness. A heating device capable of uniform sealing according to the disclosure comprises a heater for heating the sealing portion of the to-be-sealed object; a heat source supplier for supplying a heat source for heating to the heater; a heat transfer part accommodated in the heater, and transferring the heat source to the heater to heat the entire heater at a uniform temperature, and an additional heat transfer part disposed on the outer surface of the heat transfer part to conduct the heat source to the heater and in contact with the inner surface of the heater.

A shippable bundled product including a plurality of paper product rolls each individually packaged by a first package material and arranged relative to one another so as to form a bundle. The bundle is packaged by a second package material. The second package material has a shrinkage factor relative to the bundle of less than zero.

A sealing system for heat sealing superimposed walls of heat-sealable film material, e.g. in the production of pouches. The sealing section comprises two or more sealing stations arranged in series along a linear path for the superimposed walls dispensed from an infeed section. Each sealing station comprises a sealing device with first and second jaws and an actuator device to move the jaws between an opened position and a clamped position. Each sealing device comprises a motion device that is configured to move the first and second jaws in synchronicity with the superimposed walls when clamped between the first and second jaws. Each sealing station has a cooling device that is configured to continuously cool at least one of the jaws. At least each first jaw comprises at the respective front surface thereof at least one impulse heatable member embodied as a susceptor element that extends along the respective front surface. Each sealing station is configured to perform an integrated impulse sealing and cooling cycle.

An apparatus is configured to make containers from sheet material. The apparatus includes a supply station for supplying a film having at least one folded portion having three or more film flaps folded and superimposed with respect to each other; a welding station configured to receive the film. The welding station comprises a welding head configured for welding the folded portion of the film and forming a container defining a housing compartment; the welding head comprises a heater made of electrically conductive material whose electrical resistivity, at least in a predetermined temperature range, decreases upon the increase of the temperature of the same electrically conductive material.

A packaging apparatus with an improved pinch roller apparatus, fluid supply apparatus, and/or a sealing apparatus. The pinch roller apparatus (e.g., comprising one or more guide and/or pinch rollers) is used to deliver film material to the fluid supply apparatus (e.g., nozzle and blower apparatus, or the like) that fills one or more chambers of the film material with fluid (e.g., air, gas, or other like fluid), and the film material is then sealed by a sealing apparatus (e.g., using one or more heating elements with an improved temperature sensor configuration) that seals the fluid within the one or more chambers in order to form the inflated article (e.g., inflated packaging material). In particular, the sealing apparatus provides improved sealing through the improved accuracy of the temperature reading in the heating zone, in part, by locating a sensor between a heating element and a protective member that covers the sensor.

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 protective packaging formation device is provided herein. The device includes an inflation assembly having a fluid conduit that directs fluid between overlapping plies of a polymeric web. The device also includes a driving mechanism that drives the film in a downstream direction. The device also includes a sealing mechanism that includes a thin film heater that heats the plies to create a longitudinal seal that seals the plies of film together. The driving mechanism drives the web such that the web slides across the heating assembly in a downstream direction to trap fluid between the plies.

The invention relates to a welding tool and to a method for pulse welding of plastic films for medical packs formed as bags. In general, the invention provides that the film material which is plastified during welding and thus free-flowing is specifically displaced into a deepened, edge-side inner region of the sealing surface by increasing the sealing surface area. The film material accumulated in the recess leads to an increase in the film thickness in the inner region (25i) of the weld seam (6, 7, 8). As a result, the mechanical stability of the medical pack formed as a bag can be improved.

A tube welder including a clamp block configured to receive a tube, a carriage movable along a first axis, and a slide rail coupling the clamp block to the carriage such that the clamp block is configured to move along a second axis between the carriage and the clamp block. The tube welder further including a spring biasing the clamp block in a first direction along the second axis and a linkage configured to move the clamp block in the first direction and in a second direction along the second axis, opposite the first direction.
