Abstract: A carpet pad has pressure sensitive adhesive preapplied on one or both surfaces, for retaining the pad and a carpet in place on a floor by adhesion without the need for stretching. The pad or cushion in one embodiment has a film or sealant on the surfaces of the pad, with pressure sensitive adhesive on at least one of the sealed surfaces for adhering to floor surface or the underside of a carpet. In another embodiment, the pressure sensitive adhesive is a hot melt adhesive, not water-based. The hot melt pressure sensitive adhesive is applied to an uncoated porous padding surface which would be unsuitable for a water-based pressure sensitive adhesive due to excessive wicking-in of such an adhesive. An optional scrim webbing may be applied over the pressure sensitive adhesive, in either embodiment. The scrim webbing adds dimensional stability and also enables the carpet pad to be moved around on a floor or against another surface without sticking, prior to the application of pressure.

Abstract: A method of measuring the length of a lap joint between sheets of material comprises the steps of transporting the sheets over a first roll and under a second roll. The rolls are a fixed distance apart. A first signal is generated when a second end of a first sheet passes a first measuring point which is located above the first roll. A second signal is generated when a first end of the second sheet passes a second measuring point which is located under the second roll. The number of revolutions of the first roll between the first and second signal are counted by a rotary encoder associated with the first roll. By comparing the actual number of pulses counted by the rotary encoder with a reference number of pulses which is determined by the number of the rotations of the first roll necessary to transport a given point from the measuring point above the first roll to the measuring point below the second roll, a length of a lap joint can be calculated.

Abstract: A tire labeling apparatus feeds labels that are releasably adhered to a carrier web from a supply reel to a label dispensing station where the labels are transferred one at a time from the web to an application roller. At the dispensing station, the carrier web is tightly reversely bent to assist in sequentially "peeling" labels therefrom; spent web material is withdrawn from the dispensing station and collected on a collection reel; and, each newly "peeled" label is subjected to a jet of pressurized air that forces the indicia-carrying face of the label into engagement with a curved, label-receiving portion of the circumference of the application roller. Holes open through the label-receiving portion of the application roller, and ambient air is drawn through these holes to generate air pressure differential forces that releasably retain each newly dispensed label in place on the application roller.

Abstract: A tool carriage includes a main beam along which a subcarriage carrying the tool travels and is supported above a supporting table by two end parts each associated with opposite ends of the main beam. The main beam has a length sufficient to straddle the widest width of conventional supporting tables and is adjustable at one of the two end parts to accommodate different table widths. The end parts have rollers which support the carriage above the table support surface and against lateral displacement on the table. The lateral rollers on one end of the carriage are capable of being adjusted relative to horizontal and vertically extending directions allowing either end of the carriage to be generically adaptable to any table edge configuration.

Abstract: A calender for surface treatment of material webs, wherein in the event of one sided seizure of an intermediate roller the fixed roller not subject to pressure is adjusted in position at one end such that the asymmetrical linear force profile resulting from the seizure is symmetrically adjusted according to the desired condition in order to optimise processing of the material web.

Abstract: A machine for applying labels to products of various sizes employs a movable printer/applicator head. Control circuitry responsive to sensors located along a conveyor by which the products are moved toward the machine generates output signals to an electrical motor which drives the printer/applicator head at a speed defined by the processor output signals. Labels to be printed are supplied to the head from a label supply strip wound on a label supply reel mounted on the stationary part of the machine. The portion of the strip extending between the reel and the head is provided with a loop to assure sufficient length of the strip for free movement by the head. The strip is lengthened by an amount less than the length of a label each time a label is removed and is lengthened by an additional amount each time a short-loop condition is detected.

Abstract: In the fabrication of wood material panels, processed wood particles are coated with a binder free of a hardener and then are spread in a fleece on a support surface. The fleece is then compacted and pressed to form the panel. Before the compacting step, microcapsules are introduced into the fleece. The microcapsules have enclosing walls that do not react with the binder and contain a hardener in the gaseous phase or in the binary phase with a gaseous carrier agent. When the fleece is compacted, the capsule walls are destroyed and the hardener is released into the fleece. The microcapsules containing the hardener are produced in a device located adjacent to the inlet end of the press so that there is only a short distance between the device and a mixing station where the microcapsules and the bonded processed wood particles are mixed. The mixing station is located just ahead of or at the spreading station where the mixed wood particles and microcapsules are formed into the fleece.

Abstract: An applicator is utilized in applying a thermoplastic composite filament to a mandrel so as to form a structure. The filament and the surface of the mandrel are caused to move simultaneously and in a common direction relative to the applicator so that the filament is continuously fed from the applicator into engagement with the surface of the mandrel. At least one stream of heated fluid is applied to the filament so that it impinges thereon not only at location preceding the location of the applicator, but also along the length of the filament to and beyond the applicator and up to and including the region where the filament first comes into contact with the mandrel. At the same time a stream of heated fluid is applied directly to the surface of the mandrel within that region so that the mandrel is heated prior to being contacted by the filament.
