Disclosed is a system and a method for marking a continuously produced sheet of elastomeric material to identify sheet batches associated with a respective stock of raw extrusion material in a longitudinal direction of the continuously produced sheet. The apparatus includes one or more marking tools for providing the continuously produced sheet with a series of batch markings which are indicative of the respective sheet batch and for providing a start or end marking indicating the start or end, respectively, of a respective sheet batch.

An apparatus includes an extruding device configured to dispense a dielectric material though an orifice, a wire feed device configured to feed a conductive wire through the orifice, and a cutting device configured to sever the wire. It also includes an electronic controller configured to control the extruding device, the wire feed device, and the cutting device. The electronic controller commands the extruding device to dispense the dielectric material though the orifice, the wire feed device to feed the wire through the orifice, and the cutting device to sever the wire, thereby forming a dielectric substrate encasing a plurality of wires. The electronic controller further commands the extruding device to form an opening defined in the substrate in which plurality of electrically conductive wires is exposed and a location feature on the substrate located with a positional tolerance less than or equal to 1 mm relative to the opening.

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 invention relates to an apparatus for providing marks on extruded films, in particular on stretched films, which are exiting an extrusion lip of a film extruder and a respective method. The apparatus comprises at least one nozzle means for directing a gas stream, preferably an air stream to a surface of the film exiting the extrusion lip of the film extruder, wherein the nozzle means are configured and arranged in such a manner that the gas stream locally causes a cooling of the extruded film to create a local mark.

A making plastic flooring having a backing contains: a body which has a substrate, a printing layer, and an anti-abrasion layer. A method of making the plastic flooring contains steps of: (A). producing a semi-finished plastic flooring, wherein the semi-finished plastic flooring has the substrate, the printing layer, and the anti-abrasion layer; (B). moving and positioning the semi-finished plastic flooring on a predetermined position of drop plastic equipment, wherein the semi-finished plastic flooring is faced upward; (C). molding the backing, wherein the backing material is melt and is spray onto a bottom of the substrate of the semi-finished plastic flooring by using drop plastic equipment, and the backing material is adhered on the bottom of the substrate of the semi-finished plastic flooring after being solidified; and (D). cutting, wherein the semi-finished plastic flooring having the backing is removed and is cut into a desired size, thus producing the body.

The invention relates to a decorative panel, in particular a floor panel, ceiling panel or wall panel. The invention also relates to a decorative covering, in particular a decorative floor covering, decorative ceiling covering, or decorative wall covering, including a plurality of mutually coupled decorative panels according to the invention. The invention further relates to a core for use in a panel according to the invention. The invention additionally relates to a method of producing a decorative panel, in particular a decorative panel according to the invention. The invention also relates to an extruded for use in said method according to the invention.
