The invention relates to a system (10) for transporting a film tube (2) in a blown film line (1) along a transport direction, having a guiding unit (51) for guiding the film tube (2), a bottleneck (13.1) at which a width (2.3) of the film tube (2) can be reduced, a severing apparatus (20) having at least one severing element (21) for severing the film tube (2), wherein the guiding unit (51) is arranged downstream of the bottleneck (13.1) in the transport direction of the film tube (2). The invention furthermore relates to a blown film line (1) and to a method (100) for producing a film.

It is disclosed a process and an apparatus for manufacturing a figure of eight cable. An extrusion head has separate extrusion dies extruding in parallel a first and second outer sheath around a first and second core, respectively, so as to provide two separate cable elements having respective longitudinal axes laying in a first plane. While the outer sheaths are in a softened state, the cable elements are passed in parallel through a twisting die which causes their longitudinal axes to lay in a second plane forming a predetermined twisting angle with respect to the first plane. This twisting causes the outer sheaths to join together, thereby forming a figure of eight cable.

Woven irrigation tubing comprising a woven, extrusion coated & laminated tube formed of a high density polyethylene (HDPE) outer layer, a low density polyethylene (LDPE) middle layer and a linear low density polyethylene (LLDPE) inner layer. The finished tubing is treated for ultraviolet resistance. The tubing is tied off at a distal end with a proximal end connected to a pressurized irrigation source. Watering holes are created in the tubing at spaced intervals and the resulting water streams are directed into parallel plowed furrows. The tubing is completely recyclable. The tubing is formed by manufacturing tape for the woven outer tubing cover, stretching the tape along its length to strengthen it, weaving the outer layer from the tape, flattening the woven outer layer, extrusion coating each surface of the outer layer with LDPE, laminating the LLDPE inner layer to the LDPE, reversing and winding the tubing for storage and distribution.

The present disclosure generally relates to extrusion die systems. In particular, the present disclosure relates to the cyclical extrusion of materials to generate small sized grain features, generally in the range of nanosized grain features, in a tubular or profile shape, in which the individual nanolayers possess pores and/or polymer crystals oriented parallel to the extrusion flow direction and including products with enhanced permeation properties.

The present invention is concerned with a dielectric material comprising a fluoropolymer, wherein at least part of the crystalline region of the fluoropolymer is in the β-phase. The dielectric material of the present invention may show relaxor-like ferroelectricity. The present invention also relates to a novel method of producing such a material, and the use of such a material in a high energy density capacitor. The method comprises layering sheets of PVDF on one another and applying pressure to the multilayer under a temperature which is preferably within 40° C. of the temperature of fusion. Further, the film is preferably quenched.

A system for manufacturing an electrode for a secondary battery includes, a mixing unit forming a fibrillated mixture by fibrillating a powder mixture of active material powder, binder powder, and conductive material powder, a forming unit forming a mixture film by the fibrillated mixture, a pressurizing unit uniformizing a thickness of the mixture film by pressurizing rollers to form an electrode component film, first and second winding rolls each supplied and wound with the electrode component film from the pressurizing unit, a base material film roll located between first and second winding rolls and wound with a base material film, and a lamination unit configured to heat and cool to form a junction of the first electrode component film, the base material film, and the second electrode component film that are consecutively stacked.

Provided are a rubber material supplying method and a rubber material supplying device, whereby a rubber material can be smoothly supplied to a rubber inlet even when the width of the rubber material is greater than the width of the rubber inlet. The rubber material supplying method includes a separation step S1, a processing step S2, and an input step S3. In the separation step S1, a plurality of different cutouts 30 are formed in a leading end section GF of a rubber material G, and the leading end section GF is separated into three or more strip shape sections 31. In the processing step S2, second strip shape sections B, and not first strip shape sections 31A, among the plurality of strip sections 31 are each cut out or folded. In the input step S3, the leading end section GF is input to the rubber inlet 3A from the first strip shape sections 31A.

The invention relates to a method (100) for evaluating at least one industrial process for the film production of a film and/or for the further processing using the film, comprising at least one production device (20) which is operated for the production of the film, and at least one further processing device (30) which is operated for further processing using the film.

Provided is a molding hook and loop fastener, in which a barrier erected near left and right side edges of a substrate includes at least two rows of vertical wall arrays, and the vertical wall array positioned on the outermost side includes a plurality of gaps provided at a predetermined pitch in a length direction. At least two of the gaps are provided on the vertical wall array positioned on the outermost side with respect to a region between the engaging elements adjacent in the length direction of the substrate. Due to this, in the molding hook and loop fastener, an outer side and an inner side of the barrier can be divided by the vertical wall array, and flexibility of the molding hook and loop fastener can be improved.
