Separating membrane with improved adhesion and process for obtaining it
Separating membrane of plastic material, made up of a bossed and waterproof sheet which is coupled with a permeable base layer. The bosses are of the cylindrical type with a double diameter and have such a shape and arrangement as to feature improved adhesion on both faces. The gripping of the adhesive is increased in order to obtain greater tear strength, on the upper face, and at the same time increases the area of contact with the base layer for a greater resistance to delamination on the lower face. In particular, inside each chamber there is an internal crown, which divides it like a necking into two superimposed compartments having the same diameter, wherein the first compartment has a depth amounting to at least ⅓ of the total. A production process for obtaining the membrane is also disclosed.
Tire with variable ribbon size tread and system and method for making same
A method of manufacturing a tire tread includes extruding a rubber strip and conveying the rubber strip through an opening of a roller die. The opening is defined by an upper die and a lower die, wherein the upper die and lower die contact the rubber strip and define a cross-section of the rubber strip as the rubber strip is conveyed through the opening. The method also includes adjusting a distance between the upper die and the lower die as the rubber strip is conveyed through the opening. The method further includes applying the rubber strip from the roller die onto a receptacle that rotates about a receptacle axis. The method also includes translating the roller die in a first direction parallel to the receptacle axis while applying the rubber strip, thereby forming a spiral of the rubber strip about the receptacle.

MOULDING APPARATUS FOR FORMING A FASTENING DEVICE
A molding apparatus (10) for forming a retaining device. The molding apparatus (10) comprises a molding strip (12) and a molding support (24). The molding strip (12) has an inside face (14), an outside face (16), and a plurality of through cavities (18) extending from the outside face (16) to the inside face (14), the molding strip (12) extending in a longitudinal direction (X) and presenting both a transverse direction (Y) perpendicular to the longitudinal direction (X), and also a height direction (Z) perpendicular to the longitudinal direction (X) and to the transverse direction (Y). The inside face (14) is configured to press against a molding face (26) of the molding support (24), wherein the inside face (14) of the molding strip (12) and/or the molding face (26) of the molding support (24) includes an array of passages, the array of passages forming vents and connecting together the cavities (18) when the molding strip (12) is pressed against the molding support (24).
METHOD FOR FORMING A STRESS-FREE MULTILAYER PVC SHEET MATERIAL
A method for forming a multilayer plastic sheet material is disclosed, where a first polymer mass is melted under pressure and is passed through an extruder head at a specified discharge rate in the form of a plastic strand in sheet form that is provided with one or more layers so that a multilayer plastic strand is formed. This is passed to two or more rolls of a finishing stand that processes the multilayer plastic strand into a sheet. After the plastic strand in sheet form leaves the extruder head, it is first passed between a top roll and a bottom roll of a roughing stand. The speed of the rolls of the finishing stand and the rolls of the roughing stand is synchronized with the discharge rate of the plastic strand in sheet form from the extruder head, so that the plastic strand is processed without stress.
SUPER ANTI-SLIP COMPOSITE CARPET WITH THREE-DIMENSIONAL TPE ELASTIC STRUCTURE AND COMPOUNDING PROCESS THEREOF
A super anti-slip composite carpet with a three-dimensional TPE elastic structure, which is formed by compounding a fabric layer (1) and a TPE layer (2), wherein TPE is composed of 80-90% of styrene oxide-butadiene block copolymer and 10-20% of polypropylene, and the TPE layer (2) has a thickness of 1-2 mm. The compounding process thereof includes: step 1, preheating a transparent TPE to 80° C., and adding to a material barrel of a casting machine, stirring the TPE by a screw, and heating to a heating temperature of 140° C.-200° C. in 6-9 sections, to obtain a paste-like TPE; step 2, extruding the paste-like TPE through a metal joining pipe into a die head; step 3, making the paste-like TPE flow out through the die head in a planar cascade shape, and at the same time, passing the paste-like TPE flowed out from the die head together with a back part of a carpet fabric through a gap between an embossed roller and a rubber roller, so as to compound with the bottom surface of the fabric layer. The carpet has a good anti-slip effect and no edge warping, and is light resistant, aging resistant, non-toxic and tasteless, safe and reliable.
