A process for in-line extrusion of polymeric coatings onto roofing shingles during manufacturing includes moving a web of shingle substrate material in a downstream direction and extruding a liquefied coating of polymeric material onto at least one surface of the moving web to form a thin film. The liquefied coating may be a molten polymeric material that forms a thin film on a back surface of the shingle material to prevent sticking and eliminate the need for a traditional back dusting with material such as powdered stone. The polymeric film further may be applied to the substrate material in lieu of a saturation coating of asphalt, thus reducing cost and weight while providing a comparable moisture barrier and a lighter more flexible shingle.

The present invention pertains to a method to manufacture a textile product comprising a first sheet having a width and a length, and polymer yarns fastened to this sheet to form a pile thereon, the method comprising providing the sheet, stitching the polymer yarns through the sheet to form the pile on a first surface of the sheet and loops of the yarns at a second surface of the sheet, transporting the sheet in a direction parallel to its length along a heating element, the heating element being directed to the second surface of the sheet, heating the second surface with the heating element to at least partly melt the loops of the yarns to fasten the yarns to the sheet, wherein the method comprises transporting the sheet in contact with the heating element, wherein the heating element is a stationary rigid plate-like element having a width corresponding to the width of the sheet, and a length that extends parallel to the length of the sheet, the plate being curved in its length direction, wherein the outer circumference of the plate is contacted with the sheet. The invention also pertains to a method to use a textile product obtained with the new method and a device for applying the said method.

The invention relates to a tile, in particular a carpet tile. The invention also relates to the use a tile according to the invention as floor tile, wall tile, or ceiling tile. The invention further relates to a tile covering consisting of a plurality of tiles according to the invention. The invention additionally relates to a carpet covering consisting of at least one carpet tile according to the invention.

The invention pertains to a method to manufacture a textile product comprising a first sheet having polymer yarns fastened to this sheet to form a pile thereon, the method comprising providing the sheet, stitching the polymer yarns through the sheet to form the pile on a first surface of the sheet and loops of the yarns at a second surface of the sheet, heating the second surface of the sheet to at least partly melt the loops of the yarns to fasten the yarns to the sheet, wherein the method comprises measuring a roughness of the second surface with the at least partly molten loops of the yarns thereon, after the at least partly molten loops have solidified and, if the roughness differs from a predetermined surface roughness, adapting the method to manufacture the textile product, in order to obtain a second surface roughness that differs from the measured surface roughness. The invention also pertains to a device for applying this method.

Disclosed are methods and devices for forming a combined polyester and fiberglass mat, in which separate polyester and fiberglass layers can be formed or polyester filaments and fiberglass threads can be mixed together by a disperser to form a polyester and fiberglass web. The polyester filaments and the fiberglass threads can be dispersed by separate dispersers on a web forming belt to form separate layers of polyester filaments and fiberglass threads, or can be dispersed by a single disperser to at least, somewhat evenly disperse, the fiberglass threads and polyester filaments.

Coated nonwoven fibrous mats, building panels, and methods for making the same are provided. A coated nonwoven fiber mat includes a nonwoven fibrous mat having a continuous barrier coating on a surface thereof. The continuous barrier coating includes a set composition of gypsum and a binder. A building panel includes a panel core associated with a coated nonwoven fiber mat. A method of making a coated nonwoven fibrous mat includes depositing a composition of water, gypsum stucco, and a binder onto a surface of a nonwoven fibrous mat and setting the composition to form a continuous barrier coating.
