| 141 | WELDING MACHINE FOR JOINING LATERALLY OVERLAPPING WEBS OF SEALING MATERIAL | US11853054 | 2007-09-11 | US20080066870A1 | 2008-03-20 | Lukas GISLER; Adolf NIEDERBERGER |
| A welding machine for joining overlapping webs of sealing material, with a powered chassis supported by rolls, with a heating system for local heating of the webs of sealing material that is mounted laterally to the chassis (4) and can be placed between the webs of sealing material in edge regions, with at least a first pressure roll installed on the chassis for pressing together the webs of sealing material to be joined by means of heat, where a second pressure roll serving as a replacement pressure roll is placed in the chassis, whose weight rests on the drive shaft and which can be exchanged without tools for the first pressure roll that is coupled to the drive shaft of the welding machine and presses together the bitumen webs to be joined. In addition, the pressure roll (3) may have at least one contact surface made of hard metallic material; and a stripper element is provided whose free end contacts the contact surface or is in close proximity to the same. Therefore, even with materials to be welded that will contaminate the pressure roll, the welding machine is capable of operating for long periods. | ||||||

| A system for separating pieces of plastic bag from ground yard debris and the like, e.g., asphalt shingles. A conveyor conveys the debris material along a conveyor path and an agitator bounces the conveyor to cause the lighter plastic to reposition to the top of the material on the conveyor. A suction tube end is positioned over the debris material following agitation to draw the plastic off the top of the material. The tube end is selectively adjustable to enable discriminate suction effect to draw off a maximum amount of plastic and a minimal amount of nonplastic recyclable debris. | ||||||

| A method for producing asphalt fibers includes supplying molten asphalt to a rotating asphalt spinner, centrifuging asphalt fibers from the asphalt spinner, and collecting the asphalt fibers. The molten asphalt is supplied to the asphalt spinner at a temperature within the range of from about 270.degree. to about 500.degree. F. Also disclosed is a method for integrating asphalt with reinforcement fibers including the steps of establishing a downwardly moving veil of reinforcement fibers, such as glass fibers, and centrifuging asphalt fibers from a rotating asphalt spinner positioned within the veil of reinforcement fibers to integrate the asphalt with the reinforcement fibers. A method for making an asphalt roofing shingle includes the steps of assembling together a mat of asphalt fibers with a mat of reinforcement fibers, coating the assembled mats to form an asphalt coated sheet, applying granules to the asphalt coated sheet, and cutting the asphalt coated sheet into roofing shingles.

| 158 | Speed control for roof welding apparatus | US319542 | 1989-03-06 | US5072097A | 1991-12-10 | Alfred F. Miller |
| A temperature sensitive motor control for use in roofing membrane welding devices is described. The control circuit gives an output impedance responsive to variations in the temperature of the welding device and ambient temperature. A thermocouple provides a voltage signal responsive to changes in the temperature of the heating plate of the welding device. An ambient temperature sensitive circuit element acts in conjunction with the input signal to provide an output signal that is responsive to both ambient temperature and heating plate temperature. The output signal is applied to a voltage variable impedance element which outputs an impedance that is a function of both application temperature and ambient temperature. In one preferred embodiment of the present invention, the ambient temperature sensitive circuit element is a thermistor. In an alternate preferred embodiment of the present invention, the ambient temperature sensitive circuit element is a diode-comparator circuit. | ||||||

| A textile having increased porosity is made by introducing resin and microspheres or other agents for creating interstices between filaments within a yarn. The micropsheres upon heating or other agents push the filaments apart and create interstices in the yarn and bending stresses in the filaments. The resin may then be cured, holding the filaments in spaced apart relationship relative to each other and maintaining the bending stresses in the filaments. | ||||||
