A device and a method for applying cover sheets to cross-bottoms of tubular sections made of a plastic material. The device includes conveyor devices for transporting the tubular sections and for depositing the cover sheets on the cross-bottoms in a deposit area. The device includes a hot gas device with a gas heater and a nozzle connected to the gas heater and oriented toward the deposit area for the cover sheets so when gas is supplied to the gas heater, the gas flows along a flow path from the gas supply through the gas heater and the nozzle into the deposit area. The hot gas device has a hot gas reservoir with an internal volume for the temporary storage of hot gas, the flow path running through the hot gas reservoir. A gas mass flow ({dot over (m)}1, {dot over (m)}2, {dot over (m)}ges) of gas supplied to the gas heater is adjustable by a control.

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.

A sealing station configured to heat seal a wall made from heat-sealable film material, preferably metal-free heat-sealable film material, onto one another wall of heat-sealable material, e.g. another wall of heat-sealable film material, to create a sealed seam. The sealing station comprises an impulse sealing device comprising a first jaw and a second jaw, wherein at least the first jaw comprises at the respective front surface thereof at least one, e.g. a single elongated, impulse heatable member that extends along the respective front surface and that is covered by a heat-resistant non-stick covering.

The Continuous Sealing Machine for two plastic films performs continuous sealing of two films, a tubular with gussets and a plastic film, folds the gussets of the new compartment and as a result two compartment rolls are obtained, both compartments with gussets. This high performance machine provides the means for a modernization of the plastics industry. It is a machine on a main structure consisting of: Unwinders Outriggers Edge aligners Pulling roller systems Antistatic bars Antistatic bars Special device Motors with gearbox coupled to gearbox Automatic brakes Electromagnetic clutches continuous sealers Bellows former Camshaft sealers Front puller roll pitch motor Winding rods, foil positioning systems. It is part of the plastic industry machines together with extruders, printers, sealers, trimmers, raw material mixers and stencil assembly machines.

This apparatus for manufacturing a laminate comprises: a first sheet transporting device for transporting a first sheet; a water supply device for supplying an aqueous medium to the surface of the first sheet coated with a silane coupling agent and/or the surface of a second sheet coated with a silane coupling agent; and a laminating device for attaching the first sheet and the second sheet which have been supplied with the aqueous medium.

One or more implementations of a multi-layer film include a first layer non-continuously bonded to a second pigmented layer. The multi-layer film includes an unexpected appearance differing from the appearance of the pigmented layer. In one or more embodiments, the multi-layer film includes a metallic appearance despite the pigmented layer being devoid of metallic pigment. The multi-layer film also includes areas that are visually distinct from areas of the film with the unexpected appearance. The visually-distinct areas comprise areas in which the first layer non-continuously is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer or another appearance. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.

The conveyor system includes a first receiving location along a path of the conveyor system, and a dosing location along the path of the conveyor system. The apparatus also includes a first material dispensing station configured to transfer a first material to the first receiving location. The first material includes a first elastic layer and a first support layer. The first material dispensing station includes a dispenser roller configured to hold a roll of the first material, a plurality of rollers configured to convey the first material from the dispenser roller to the first receiving location, and a stripper plate configured remove at least a portion of the first support layer from a portion of the first elastic layer.

A protective packaging formation device is disclosed herein. The device includes an inflation assembly that directs fluid between first and second overlapping plies of a web material. The device also includes a sealing mechanism that includes an arcuate web-support surface. The web-support surface includes a heater that defines a heating zone that is operable to heat the plies to create a longitudinal heat seal that seals the first and second plies together as the web is driven over the heating zone in a downstream direction. The web-support surface also includes a cooling zone disposed downstream of the heating zone operable to allow the heated plies to cool at the longitudinal heat seal as the web is driven over the heating zone in a downstream direction, such that the cooled longitudinal heat seal retains the fluid between the plies.
