Method for the production of an insulating profile
A method for producing insulating profiles comprises manufacturing a profile body and a first functional element separately, and the profile body and the first functional element are supplied to an ultrasonic welding device, wherein the profile body and the functional element are connected to one another by a material bond by formation of a welded joint. The profile body and the functional element are brought together into a predetermined first cross-sectional geometry during formation of the welded joint and are thereafter guided in this cross-sectional geometry until the plastics material of the welded joint solidifies to such an extent that the profile body and the first functional element are fixed in the predetermined cross-sectional geometry.
Method for producing fiber-reinforced plastic components
Disclosed is a method for producing components from fiber-reinforced thermoplastic. The method involves manufacturing a multitude of semifinished products, each of which includes a plurality of impregnated fabric layers that are joined to one another only locally, as well as a frame structure having at least one cutout. The semifinished products are consolidated using a consolidation device, an inlay element being placed in each cutout before the semifinished products are consolidated.
HEATING DEVICE FOR A HEATING AND SEALING SYSTEM
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.
DEVICE FOR CONTINUOUSLY DOSING PLASTIC MATERIAL, ESPECIALLY FOR A UNIT FOR PRODUCING COMPONENTS MADE OF PLASTIC MATERIAL OR THE LIKE
A dosing device for dosing plastic material, comprising an extrusion head that has a dispensing opening commonly called a die and a punch extending into the dispensing opening, coaxially thereto, for continuously extruding a plastic material in the form of a tubular or annular body, and a cutter for separating a dose of said plastic material in the form of a tubular or annular section. The cutter includes at least two elements having at least one cutting edge extending on either side of the dispensing opening and secured to a driver for symmetrically moving the at least two elements in relation to a longitudinal axis of the extruded tubular body until the tubular body is severed by said at least two elements in order to form a dose.
APPARATUS AND METHOD FOR SECURING A ZIPPER CLOSURE TO POLYMERIC FILM
A method and apparatus for securing a zipper closure to polymeric film using minimal tension on the zipper closure includes providing first and second tension control loops, an eyemark detector, and a hole punch programmed to punch a hole in the zipper closure upon detection of the eyemark. The zipper closure and the film are supplied to a sealing station at the same speed, and the hole zipper closure is aligned with the eyemark on the film, to result in sealing the strip of zipper closure to the film resulting in minimal wrinkles to the resulting bag.
HEAT SEALING SYSTEM
The technology relates to a heat sealing system. For instance, the heat sealing system may include a sealer assembly including a pair of heat sealing bars configured to generate heat seals. The heat sealing system may also include a positioning assembly including a platform and a motor. The sealer assembly may be mounted to the positioning assembly, and the motor may be configured to move the sealer assembly towards and away from an edge of the table.
Film edge sealing device
A film fin sealing device is disclosed herein which may have a groove defining a base. The base of the groove of the fin sealing device may be oriented at a skewed angle with respect to a longitudinal direction of the conveyor of a heat sealing machine. Edges of a thermoplastic sheet or two stacked layers of thermoplastic sheets are introduced into the groove of the film fin sealing device and placed in contact therewith to both heat and fuse the distal edge portions of the thermoplastic sheet(s) to join the edge portions thereof to form a fin seal.
METHOD OF MAKING A RETORT CONTAINER
A method is described for making a retort container having one or two metal ends. A heat-sealable material is present on one or both of the container side wall and the/each metal end. The/each metal end is seamed onto the container body, and the resulting container assembly is conveyed on a conveyor adjacent to an induction sealing head and then adjacent to a cooling device. A pressure belt engages the upper end of the container assembly to keep the metal end from coming off the container body during the induction heating and cooling processes.
Device for storing and removing cardboard for a bridge in a corrugated cardboard production line
A device for cardboard storage and removal for a bridge in a corrugated cardboard production line includes a bridge over which a conveyor system for conveying the single-sided laminated corrugated cardboard web is arranged. The exit end of the conveyor system for conveying the single-sided laminated corrugated cardboard web is provided with a clamping and cutting unit and a movable cardboard storage carriage unit is provided under the conveyor system for conveying the single-sided laminated corrugated cardboard web, under which conveyor system a conveyor belt system is provided in the bridge, and in the bridge an opening is provided, under which a waste cardboard collecting carriage is provided. The movable cardboard storage carriage unit stores the cardboard by means of cardboard storage rolls, which retain the single-sided laminated corrugated cardboard web flat on the bridge. In the event that a splicing defect is detected, the defective piece is cut out by the clamping and cutting unit and ejected by the conveyor belt system to the waste cardboard collecting carriage through the opening. Hence, it follows that productivity is improved.
