Retainers for the film web are arranged on the two lateral edges. The retainers are each formed by a fixed clamping surface and at least one clamping jaw, which is movable relative to the clamping surface, for pressing the film web so as to clamp it against the clamping surface. The retainers also each have at least one retaining magnet for attracting the clamping jaw against the clamping surface, and an actuating extension for lifting the clamping jaw off the clamping surface. The film transportation system also includes actuating means which act on the actuating extensions of the clamping jaws.

APPARATUS AND METHOD FOR APPLYING COVER SHEETS TO ENDS, PREFORMED INTO CROSS BOTTOMS, OF TUBE PORTIONS
20220024152 · 2022-01-27 ·

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.

Method and System for Forming Packages
20220024170 · 2022-01-27 ·

A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

PROCESSES FOR MAKING RECYCLABLE CELLULOSE BASED INSULATED LINERS
20220017288 · 2022-01-20 ·

Process to produce a recyclable insulating liner, the process comprising folding a web of cellulosic material in half, thereby forming a folded web comprising two side edges a top edge and a bottom folded edge; connecting at least one of the two side edges along an intra-panel connection line to form a pouch comprising two bottom corner portions; cutting out a parallelogram-shaped section in each of the two bottom corner portions, thereby forming a cut pouch comprising two unconnected bottom corner sections comprising free edges; and expanding the cut pouch and connecting the free edges of both unconnected bottom corner sections to form straight edges.

Bottle pouch with rigid handle
11220373 · 2022-01-11 · ·

A bottle pouch with an integrated fitment and inner support handle piece includes a flexible pouch in the shape of a bottle including a flexible pouch body with a handle region, and a combined fitment and inner support handle piece including a rigid handle portion extending from the combined fitment and inner support handle piece. The combined fitment and inner support handle piece is coupled to the flexible pouch. The inner support handle piece extends from the inside of the fitment and is internal to the flexible pouch body and passes from the interior to the exterior of the flexible pouch body adjacent to the handle region of the flexible pouch body to form the rigid handle portion. In another form, the inner support handle piece extends from the outside periphery of the fitment and is external to the flexible pouch body, but is secured to the periphery of the flexible pouch body with one or more outer sleeves or loops.

Method And Apparatus For Pouch Or Bag Making

A method and apparatus for making bags or pouches is disclosed. It includes a track, at least two sleds that move on the track, and operating stations mounted on the sleds. The film moves along the track, and the sleds move with the film while performing operations on the film. The system can have the sled stationary while operating for an intermittent machine, and move to reconfigure when the film is moving. The operating stations include one or more of a sealer, a heater, a cooler, an inserter, a knife, a punch, a perforator, a static charger, and a printer. The track forms a continuous path or is linear. A controller controls the sleds and operating stations. The controller includes an operating time and/or a reconfiguration module. The operating time module is responsive to a user set material thickness or a sensed material thickness.

MACHINE FOR PRODUCTION OF STAND UP POUCHES
20210347141 · 2021-11-11 ·

A machine for the production of a stand up pouch from a web includes a film feed which moves the web at continuously at a constant speed through a punching station, a folding station, and a welding station. The welding station includes a pair of seal bars which are driven by a server motor at a speed equal to a speed of the web during the welding. The punch station includes at least one electromagnetic punch.

Spindle-shaft unit for a device for the rotary closing of containers with a screw closure
11167970 · 2021-11-09 · ·

A spindle-shaft unit for closing containers with a screw closure includes a spindle that is rotatable and axially movable relative to a housing and a bearing unit arranged between the housing and the spindle. The bearing unit comprises a sliding bearing that interacts with the spindle and a further bearing that interacts with the sliding bearing. The spindle is arranged at the sliding bearing such as to be displaceable and non-rotatable relative to the sliding bearing. The further bearing secures the sliding bearing so as to be rotatable and non-displaceable relative to the housing.
