Abstract: A conveying mechanism for a non-woven carpet machine which includes a pair of conveyor belts along each edge of the backing material for pulling the backing material from its roll and pushing it toward a portion of the machine where bonding material is applied to the backing material. Hot air from the curing oven can be directed against the backing material after the bonding material is applied thereto to make the bonding material tacky so that when yarn is embedded in the bonding material it will not easily be pulled out.A mechanism for advancing the backing material includes means for intermittently pulling the backing layers at a constant rate of speed through the well of the machine and oven and past the cutting mechanism, while a pin roller engages the backing material before the well. An adjustable torque controlled motor is connected to the pin roller so that a constant tension is maintained in the backing material.

Abstract: A web-like fibrous material consisting of fibres standing on end is produced from a starting material consisting of a web-like fibrous material, in which the fibres are oriented substantially transversely or longitudinally of the web. The starting material is cut into strips which in well-known manner are arranged side by side with the fibres standing on end. It is the object of the invention to eliminate the spaces or interfaces between these strips in a more efficient manner than has hitherto been possible. To this end, the side-by-side pattern of strips is deposited on a moving intermediary supporting surface, on which they are retained by an attractive force directed towards said surface and are at the same time subjected to a spreading action transversly of the strips, whereafter the fibres are deposited at a second depositing position on a moving product receiving surface while at the same time interrupting the attractive force acting on the fibres being deposited.

Abstract: A pile weatherstripping has a continuous length of a resin anchorage base with even lengths of filaments secured to opposite sides of the base along the length of the base and extending away from the base in the same general direction on each side of the base. The filaments are long enough and dense enough to form insulating pile rows extending out of a retainer slot in which the anchorage base has an interference fit. A sheet resin fin preferably extends continuously outward from the base between the filaments on the opposite sides of the base, and such a weatherstripping is preferably made by wrapping a multifilament yarn around a plurality of bases, securing the yarn to opposite sides of the bases, and then slitting to separate each individual weatherstrip.

Abstract: To produce a pile fabric, particularly a pile carpet, a fibrous batt, in which the fibres are transversely oriented, is cut into longitudinal strips which are then turned through an angle of 90.degree. about their longitudinal axes by means of pairs of conveying wires, which run in paths from oppositely located guiding grooves of a pair of input rollers to guiding grooves located side by side in the surface of a depositing roller by means of which the fibres, which are now standing on end, are applied to an adhesive backing.

Abstract: This invention relates to a method and apparatus for making pile fabrics wherein a sheet of longitudinally striated thermoplastic film formed into loops is fusion bonded to a thermoplastic backing sheet by sonic energy to bond the film to the backing sheet at the lines of contact without loss of orientation in either the striated film or the backing sheet and then subsequently the bonded striated film is fibrillated to separate the loops into individual filaments thereby forming a pile fabric.

Abstract: Production of pile fabric with repetitive cutting of incremental lengths of fiber with a moveable cutter. The increments are sequentially packed onto a guide, such as a shaft conveyor, and then delivered to and implanted on an adhesive coated carrier or backing moving on a carrier conveyor. To prevent disordering of the fibers, the fiber is caused to retract from the cutter upon retraction of the cutter.

Abstract: The present invention is concerned with a machine for producing non-woven "glued" carpets and particularly with operating mechanism for alternately pressing a "pile-yarn" sheet against one and then the other of a pair of opposed adhesive-carrying backing layers or sheets between which the pile-forming fibrous materials or yarns are fed as in the form of a longitudinally advancing warp sheet moving concurrently with the backing sheets. After setting of the adhesive layers, which generally is effected during their concurrent advance, the intervening pile-forming sheet is cut to form two non-woven cut pile-surfaced carpets, in each of which the pile "yarns" project from the backing fabric or layer to which the pile is adhered. The present invention is particularly concerned with the mechanism for driving the presser bars, blades or plates alternately against opposite sides of the pile-forming sheet and thereby pressing the latter sheet against the adhesive-coated surface of the backing layer or sheet.

Abstract: A machine for making carpeting in which rows of lengths of yarn are bonded to an adhesive surface of a backing web has a gripper station at which yarn ends are presented in a row and are drawn out a predetermined distance, the drawn length of yarn being engaged to support them and then cut off. The cut lengths are then transferred to an assembly station where they are placed on the adhesive surface of the backing. The yarn lengths are pressed against the adhesive surface by a bladed member. The means engaging the drawn yarn lengths to support them comprises, in a preferred version, a bar extending along one side of the row of yarn ends and provided with a multiplicity of pins for impaling the yarn lengths, and a bar on the other side of the row with holes corresponding to the pins for pressing the yarn lengths on to the pins.

Abstract: A method of making pile fabrics in which a compacted block of strands of pile forming material is incrementally discharged from an open end of a container in successive increments of an amount equal to the desired length of pile and, following each discharge of the block from the container, a pile slice is severed from the block while being deposited directly onto and secured to an advancing layer of adhesive carried by a release surface to form a pile fabric of cut pile tufts secured to an adhesive substrate which is then removed from the release surface.

Abstract: An oriented thermoplastic sheet is pleated and an adhesive and backing is applied to one face thereof. The other face is then pleat fibrillated to a desired depth. Both faces may have adhesive and backing applied thereto with the structure being centrally cut parallel to the faces. The extending edges of the sheets on the two structures are then fibrillated to a desired depth.

Abstract: A web formed of a multiplicity of general parallel fibers or filaments is fed downwardly and incrementally toward a platen forming a lower element of a generally horizontal guide. A shear periodically moves across the path of the web so as to shear from the end thereof a section having a length slightly greater than the height of the guide. The lower edge of the upper element of the guide constitutes one of the shear elements so that as each section is cut off it is pressed into the end of the guide. Simultaneously with each cutting operation the stack formed in the guide is moved incrementally toward the downstream end thereof. As the stack emerges from the downstream end the sections are pressed end-wise into an adhesive layer on a substrate.

Abstract: A tufting machine having multi-color selection capability for each tufting cycle which utilizes pneumatic pressure, either positive or negative, or a combination of the two, to transfer the yarn or other tufting material to tufting elements. The system comprises yarn guide passageways having abutting sections which are relatively movable to create an opening through which a yarn severing means severs the yarn into selectively-sized bit lengths. The relative positions of the yarn severing means and the abutting sections of the passageways are adjustable to provide yarn bit lengths of selectable varying lengths. A combination bit applying element and clamp means is utilized to apply the yarn to an adhesive bit gripping surface on the backing layer. In the preferred embodiment, this application occurs before the yarn is severed and thus the yarn is effectively clamped at the time of severance.
