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.

A method and apparatus for producing elastic laminates wherein a first and a second elastic film are stretched in the transverse direction by respective spreader devices, and are applied on a transfer wheel which—in turn—applies the first and second elastic films on a non-woven web held on the outer cylindrical surface of an anvil wheel.

An apparatus for producing at least one PLA tape includes a heating device for heating a tapelike extruded PLA film. The apparatus further includes a slitting device for slitting the PLA film heated by means of the heating device into the at least one PLA tape. The apparatus further includes a control unit which is configured to control the heating device in such a way that the PLA film is heated by the heating device to a PLA temperature in the range from 40 to 70° C. The apparatus further includes a drawing device downstream of the slitting device.

A method for manufacturing a fiber-reinforced composite material molded article of the present invention includes a step of causing a reinforcing fiber base material to undergo deformation with use of a mold, the reinforcing fiber base material including: reinforcing fibers which are unidirectionally oriented; and a matrix resin composition. The reinforcing fiber base material has a cut in a zone which is to undergo shear deformation and/or compressive deformation, the cut being substantially parallel to an orientation direction of the reinforcing fibers, and has substantially no cut that cuts through a fiber.

A wearable container containing a composite which has an alternating pattern containing groupings of woven fabric and groupings of biaxially oriented thermoplastic films. The composite has a thickness of less than about 5 mm. Each grouping of woven fabric contains at least one woven fabric layer, each woven fabric layer containing tape elements having a base layer of a strain oriented olefin polymer disposed between covering layers of a heat fusible olefin polymer. Each grouping of biaxially oriented thermoplastic films contain at least one biaxially oriented thermoplastic film which has a core layer of thermoplastic disposed between covering layers of a thermoplastic able to bond to polypropylene.

Methods for producing a stretch film are provided, including disposing one or more extruders in fluid communication with a stock of virgin resin; heating the virgin resin to a molten state; delivering the molten virgin resin to a die; and extruding the molten virgin resin through the die onto a casting roll, thereby creating a cast stretch film. Methods for delivering the molten virgin resin onto a casting roll of varying sizes and set temperatures; and of moving a resulting film onto a secondary chill roll of varying sizes and set temperatures, are also provided. Finally, methods for moving the film from either the casting roll or the secondary chill roll onto a slitting assembly, dividing the film using one more interior or exterior slits, and then capturing and gathering the trim waste but not reintroducing the trim waste back into the production process are also disclosed.

A repair patch is for a composite material to repair a part to be repaired which is a repair target of the composite material. The patch includes a patch main body that is formed by laminating a plurality of fiber reinforced preforms in a thickness direction, and has a bonding surface to be bonded to the part to be repaired; and a removal layer that is provided on the bonding surface to be peelable off from the patch main body. The bonding surface includes an inclined surface that is inclined with respect to the thickness direction of the patch main body. The removal layer includes a processed portion that causes the removal layer to have a shape complementary to a shape of the inclined surface of the patch main body

Biodegradable self-expanding polymer stent has an outer diameter of 0.25-40 mm, length of 5-250 mm, and closed-cell wall structure formed by struts, where ratio of inner diameter values before crimping and after crimping is in a range of 3 to 5, and made of a copolymer obtained from L-lactide, D-lactide, D,L-lactide, meso-lactide, glycolide, ε-caprolactone, trimethylene carbonate, p-dioxanone and compounds comprising functional groups capable of photopolymerization; supramolecular structure of the copolymer is oriented substantially circularly in a transversal cross section of the stent. Method of manufacturing includes extruding a tube of a polymer material; annealing the extruded polymer tube; laser cutting the extruded polymer tube to form a stent workpiece; heating the stent to above glass transition temperature of the polymer, crimping the stent workpiece uniformly over the entire outer surface thereof, and quenching at about minus 20 degrees Celsius; placing the quenched stent on a delivery means.

A method of making a barbed microcatheter having fluid egress openings includes obtaining a barbed microcatheter blank having a hollow tube with a proximal end, a distal end, and an elongated lumen that extends between the proximal and distal ends of the hollow tube, and first and second flattened regions that extend along opposite sides of the hollow tube. The method includes removing material from the first and second flattened regions of the barbed microcatheter blank to form barbs projecting outwardly from the opposite sides of the hollow tube, and using cutting elements for forming fluid egress openings in a wall of the hollow tube that are in fluid communication with the elongated lumen of the hollow tube. The method includes forming a tissue anchor that is connected with the proximal end of the hollow tube, and securing a surgical needle with the distal end of the hollow tube.

A production method for fiber-reinforced plastic, includes: a step in which a material (A) including a prepreg base material is obtained, said prepreg base material having cuts therein and having a thermoplastic resin impregnated in reinforcing fibers arranged in parallel in one direction; a step in which a pressurizing device is used that applies a substantially uniform pressure in a direction (X) orthogonal to the travel direction of the material (A) and the material (A) is caused to travel in the one direction and is pressurized while being heated to a prescribed temperature (T), an angle (θ) of −20° to 20° being formed between the orthogonal direction (X) and a fiber axial direction (Y) for the reinforcing fibers of the prepreg base material; and a step in which the material (A) pressurized by the pressurizing device is cooled and the fiber-reinforced plastic is obtained.
