Method for Measuring Overlaps in Prepreg Materials
An assembly to connect together first and second sheet members. The assembly includes a pressure device that applies pressure to the sheet members while the sheet members are in an overlapping arrangement and positioned on a support platform. A sensing system that includes one or more thin film pressure sensors detects the positions of the leading and trailing edges. A connection device connects the members together in an overlapping arrangement.
METHOD FOR PRODUCING WEBS FOR REINFORCEMENT PLY OF A TIRE BY BUTT-JOINING STRAIGHT-WIRE STRIPS
The present invention relates to a method for manufacturing webs (1) that are intended to be involved in the makeup of a reinforcing ply (2) for a pneumatic tyre (20), said method comprising a preparation step (a), during which a plurality of straight-thread strips (7, 107, 207), which are each formed of a plurality of continuous reinforcing threads (4) that are embedded in a layer of rubber (5), are prepared, a butt-joining step (b), during which said straight-thread strips (7, 107, 207) are butt joined in pairs to form a straight-thread ply (3), then a cutting step (c), during which the straight-thread ply (3) is inserted into a cutter (8) and the straight-thread ply (3) is severed transversely so as to form webs, wherein, in said method, the frontal width (W3) of the straight-thread ply (3) that is produced during the butt-joining step (b) and then inserted into the cutter (8) is equal to or greater than 50%, equal to or greater than 75%, equal to or greater than 80%, or even equal to or greater than 90%, of the cutter inlet width (W8), whereas the widest frontal width (W7, W107, W207) of the straight-thread strips is less than or equal to 50%, less than or equal to 40%, less than or equal to 25%, less than or equal to 10%, or even less than or equal to 5%, of said cutter inlet width (W8).
Joining device and method for joining strips to form a tire component
Disclosed is joining device for joining a trailing end of a first strip to a leading end of a second strip to form a tire component. The joining device includes a support member with a support surface and a retaining member with a retaining surface for retaining the second strip. The joining device is arranged for positioning the leading end of the second strip in a joining orientation in which said leading end is closer to the support plane than the rest. The joining device also includes a control unit for controlling a relative movement between the support member and the retaining member with a first component in a placement direction to place the leading end of the second strip and a second component in a joining direction to bring the leading end of the second strip into contact with the trailing end of the first strip.
Methods for reinforcing a multi-panel support mat
A method of reinforcing a support mat includes at least one extruder applying at least a first stream of weld-forming material over at least one seam formed between upper and lower, interconnected, at least partially overlapping, panels on the top of the mat and at least one automated extruder applying at least a second stream of weld-forming material over at least one seam formed between the panels on the bottom of the mat.
METHODS OF JOINING AND REPAIRING COMPOSITE COMPONENTS
A first thermoplastic component and a second thermoplastic component including a first joint portion and a second joint portion, respectively, are provided. A least a portion of a surface area of each of the first and second joint portions include a respective first and second mating surface. The first and second mating surfaces of the respective first and second joint portions are positioned in contact with one another. The first and second joint portions are fusion joined. Fusion joining the first and second joint portions forms a fused unitary portion of the first and second thermoplastic components.
Ultrasonically welded mat unit and system thereof
A mat unit includes a plurality of gaps defined by a first layer that are in open communication with gaps defined by a second layer so as to permit debris to fall entirely through both gaps to pass completely through the mat unit. The mat unit is part of an omnidirectional mat cleaning system that includes a first direction of travel above the mat unit extending through a door opening defined by a building structure. A different second direction of travel is above the mat unit extending through the door opening or another door opening defined by the building structure. The mat unit is installed on a floor adjacent the door opening. The mat unit cleans shoes regardless of the direction of travel traveled above the mat unit.
ROOFING THERMAL WELDER EXTENSION MARKING TOOL
A thermal welding marking system for attachment to a thermal welding machine including: a hammer arm rotatably connected to a mounting bracket attached to the thermal welding machine, wherein a distal end of the hammer arm is shaped to receive a marker or pen therein; a cable or spring connected to the distal end of the hammer arm; a cable connecting the hammer arm to a hand lever mounted adjacent to hand controls on the thermal welding machine, wherein movement of the hand lever raises or lowers the distal end of the hammer arm and thereby raises or lowers the marker or pen therein. In operation, the thermal welding machine is advanced across the edges of overlapping building roofing material and the marker or pen is intermittently lowered/raised to mark locations along a seam of the edges of overlapping building roofing material where the seam is either open or closed.
Machine and process to automatically reconfigure composite tape and fabric
A system to re-configure an input material into an output material includes an input material feeder reconfigurable to accept and feed an input material, an output material spooler, the input material feeder re-configurable relative to the material cutter to cut the input material at a re-configurable cut angle to produce a first intermediate cut section of material, a positioning and alignment system to position and align a leading edge of the first intermediate cut section of material with a trailing edge of a second intermediate cut section of material, a welder having a configurable position to weld the first intermediate cut section of material to the second intermediate cut section of material, and a control system comprising logic to set at least intensity of the welder, a contact pressure of the welder, temperature of the weld-table surface, and a tension applied by the output material spooler.
Method and apparatus for welding a roofing membrane
A machine for welding an overlapped region of two adjacent strips of material and a method of using the same. The machine includes a housing with front and rear ends, a wheel train engaged with the housing for moving the housing across the material; a nozzle on the housing having a welding head at a free end; the nozzle being positionable at least partially beneath the housing's bottom wall for welding the overlapped region; front and rear pressure rollers engaged with the housing, where the front roller is positioned forwardly of the welding head and the rear roller is positioned rearwardly of the welding head; wherein the rear pressure roller applies pressure to the overlapped region when the wheel train moves the housing in a forward direction; and the front pressure roller applies pressure to the overlapped region when the wheel train moves the housing in a reverse direction.
Method of seaming carpet
A method for joining two carpet segments, each carpet segment having an underside and at least one edge, comprises abutting one edge of one carpet segment with one edge of the other carpet segment, positioning a length of seam tape under the abutting edges, and activating the adhesive to secure the seam tape to the undersides of both carpet segments. The seam tape comprises an elongated base layer being resilient in a longitudinal direction, an intervening layer applied to the base layer, and an adhesive applied to the intervening layer.
