摘要： The present invention relates to an apparatus for producing inline stretched tubular foils by the blowing process, having a blown foil system comprising an extruder, a blowing head, a cooling ring, a calibrating basket, a flat laying unit and a reversing turret haul-off, having a stretching system for monoaxially stretching the laid flat foil in the machine direction and with a first thinness control system which operates segmented control zones in the cooling ring to form thinness sections so that, during stretching, a foil is produced with a thickness profile having the smallest possible deviations from the medium foil thickness over the complete foil width. To increase the accuracy and speed of the first thinness section control system, a second thinness section control system is provided which controls two opposing heat sources between the calibrating basket and the flat laying unit and which can be connected to the first thinness section control system.

摘要： The invention relates to a method for a model-based determination for processing an order inquiry (AA) by means of a production model (PM) of a film extrusion line (10), comprising the following steps:
Capture at least one model parameter (MP) in the form of an output parameter (AP) of the production model (MP) to capture a requested film product property of the order inquiry (AA),
Forming a parameter relationship between the detected at least one output parameter (AP) and at least one model parameter (MP) in the form of an input parameter (EP) of the production model (PM) for determining a production situation of the film extrusion line (10),
Generating at least one input parameter (EP) of the production model (PM) based on the formed parameter relationship as a default for a production process on the film extrusion line (10).-

摘要： The invention relates to a method for automatically regulating the size of a nozzle discharge slot of a nozzle assembly, wherein the nozzle assembly comprises a first and a second nozzle lip and a nozzle discharge slot arranged between the nozzle lips for setting in a controlled manner a thickness profile of a conveyable melt. A plurality of adjusting elements, in particular a plurality of adjusting pins, coupled to a respective thermoelement, is arranged on the first nozzle lip, the thermoelements being controllable by the regulation in such a way that the slot can be adjusted by the action of a mechanical force from the respective adjusting element on the first nozzle lip, as a result of the expansion or contraction of the thermoelements. At an initial operation of the nozzle assembly for conveying the melt, the adjusting elements for subsequent regulation of the slot size are set uniquely free from play as the initial setting. The invention further relates to a control and/or regulation system.

摘要： The invention describes a pouch-type bag, with a first wall and with a second wall, which comprise paper and which are connected to one another via side edges, so that a filling space is provided, wherein the second wall, viewed in the longitudinal direction of the pouch, protrudes beyond the first wall, with two ends, wherein a base is arranged at one end, which base comprises at least one envelope area of the second wall, wherein the envelope area is folded over about a first crease line at least onto parts of the first wall, wherein an opening is provided at the other end, via which opening the filling space is accessible, wherein one of the walls comprises a sealing area which can be folded over about a second crease line onto the outside of the other wall and can be fastened there by means of an adhesive element applied to the sealing area.
The sealing area comprises a tear-off aid between the second crease line and the adhesive element, with which the sealing area can be at least partially severed to allow renewed access to the filling space.-

摘要： The invention relates to a blown film system for producing a film tube made of plastics material, comprising: an annular nozzle, out of which a plastic melt having a closed cross-section can be brought; a take-up device, by means of which the plastic melt can be drawn up from the direction of the annular nozzle so as to form the film tube; an air-provision device, which is downstream of the annular nozzle when viewed in the transport direction of the film tube and by means of which an amount of air can be provided; and a calibration device, which is downstream of the annular nozzle when viewed in the transport direction of the film tube and surrounds the film tube and by means of which the outer circumference of the film tube can be delimited. At least one detector is contained that has a plurality of detection elements, by means of which electromagnetic radiation emitted or reflected at various points of the film tube can be detected, such that at least one planar region and/or contoured region of the film tube can be detected with regard to characteristic properties, wherein the detector comprises at least 32 detection elements.
