A scuff-removing pad is provided that includes a piece of vinyl or linoleum sandwiched between two similarly shaped pieces of adhesive backed felt. The materials are pressed together using 15 tons of pressure for maximum adhesive and then die cut to form the shape of the scuff-removing pad. Each pad has a small through hole to allow for the insertion and tying of a tether which is tied at an opposite end to a clip or other device for removable attachment to a custodian's belt. The scuff-removing pad is useful for the custodian to erase scuff marks from vinyl flooring or other solid flooring.

A method of manufacturing a laminated steel plate capable of simplifying the manufacturing process. This is achieved by a method of manufacturing a laminated steel plate including a step of applying a mixture containing an oil and an adhesive composition for a laminated steel plate including at least one kind of a (meth)acrylate compound compatible with the oil and an organic peroxide to one side or both sides of a strip-like steel plate; and a step of punching a steel plate body from the strip-like steel plate with a punch portion of a press forming device, and laminating and bonding the steel plate bodies.

A method of forming an electric machine lamination includes punching a sheet having a first composition to form a cavity and a compressed region at a perimeter of the cavity. The method further includes depositing, within the cavity and on the compressed region, a deposit material having a second composition different than the first composition. The method further includes scanning a beam along the deposit material to form a bound material within the cavity and on the compressed region.

Liner having an induction heat sealable layer for sealing to a rim of a container, and a pull tab for ease of removal of the liner from the container rim. An insert is disposed between multilayer upper and lower components, has a heat bondable polyolefin layer that is thermally laminated to polyolefin layers of the upper and lower components, forming a pull tab between the integrated polyolefin layers. The resulting composite resists delamination and can be formed in a single thermal lamination step, avoiding the multiple lamination steps, associated high equipment costs, and complex layer constructions of the prior art.

The invention refers to a process to manufacture multilayer laminated packaging material. More particularly, the invention relates to processes to manufacture multilayer laminated packaging material used to produce carton packages, in especially aseptic carton packages containing liquid or pasty products. A plurality of layers is continuously laminated onto a non-printable face of a paperboard layer to form a semi-finished web of multilayer laminated packaging material. Next, the inner face of a translucent thermoplastic protective material having a commercial artwork printed onto its printable inner face is laminated onto the not printed printable face of said semi-finished web of multilayer laminated packaging material, wherein the artwork with numbers, letters and drawings is printed in a reverse position regarding to what was supposed to be when seeing the artwork from the opposite not printed outer face of said translucent thermoplastic protective material.

Disclosed herein are plaster boards that include first and second layers of hardened plaster material, a liner attached to the first layer of hardened plaster material, and a first material (e.g., a polymer material such as a viscoelastic polymer) adhered between the liner and the second layer of hardened plaster material. The liner includes one or more structurally weakened regions each extending substantially from a first edge to a second opposing edge of the plaster board. The structurally weakened regions of the liner may facilitate creation of a fissure that propagates substantially within a plane within the plaster board. Methods for making the plaster boards may involve drying wet plaster material while it is in contact with a liner having structurally weakened regions, processing a liner to form its structurally weakened regions while in contact with wet plaster material, or processing a liner to form its structurally weakened regions while in contact with hardened plaster material.

The invention relates to a method for producing an RFID label for use in particular on curved metal surfaces and on containers filled with liquids in the frequency range 860-960 MHz, having a substrate on which are arranged an electronic storage and transmission device designed as a microchip, a primary antenna galvanically connected to the microchip, and a secondary antenna coupled to the primary antenna, wherein the substrate is designed as a continuous strip in roll form which can be processed by machine with a plurality of secondary antennas arranged thereon, a first variant being characterized by the following steps: —punching the secondary antenna out of a conductive metallic layer, preferably a self-adhesive aluminum foil, and covering the secondary antenna with a preferably transparent self-adhesive film, in particular a polypropylene or polyethylene film; —punching a web out of a self-adhesive foam film; —applying the primary antenna to the covered secondary antenna at a position intended therefor and laminating a self-adhesive top material to a partial region of the upper side of the covered secondary antenna; and—applying an adhesive to a partial region of the upper side of the covered secondary antenna, laminating the unit consisting of the primary and secondary antennas to the self-adhesive foam film, and punching out the RFID label intended for subsequent folding.

A manufacturing process of EPC composite structure floors which includes an LVT layer and a substrate layer from top to bottom includes steps of separately and independently preparing the LVT layer and the substrate layer, and performing stacking and attaching the LVT layer and the substrate layer with glue so as to obtain finished products of the EPC floors. The substrate layer needs to be subjected to a working procedure of tempering before being stacked and attached with the LVT layer. The EPC floors manufactured by the process completely meet ISO standard requirements, and when being maintained in an environment of 80° C. for 6 hours, the WPC floors can also maintain a size change rate of 0.15% or below.

An electric machine includes a plurality of planar laminations stacked to form an electrical steel rotor having openings defining magnet pockets and adjacent inner side pockets. The adjacent inner side pockets define a center bridge therebetween and have blasted surface portions such that compressive stress layers are induced along edges of the center bridge to strengthen the center bridge.
