Abstract: The tools for the restoration of deformed lamina require a series of capable of being deformed plaques (1,5,12,13,14,18,18') provided with a central post or a stem (3,7,9,19,19') which are fixed by glues or adhesives with the use of an applicator (22,23,24), on the exterior of the deformed area of the lamina. They are therefore pulled through the post (3,7,9) and stem (19,19') towards the outside through the extractor (28,34), thus restoring the deformed plate (17). When the restoration has been completed the lamina is detached and possibly recovered for further use.

Abstract: A latex balloon neck is pretreated by refreshing a region (18) of the inner surface (16) of the neck. The refreshed region extends substantially entirely around the inner circumference of the neck. The refreshing consists of cleaning the latex surface with a solvent e.g. isopropanol. The balloon neck is sealed by pressing (e.g. pinching and/or stretching) opposed areas of the refreshed surface (18) into direct contact with each other to form a latex-latex bond without requiring any additional adhesive coating. A removable protective tape (20) is placed over the refreshed region (18) to prevent the refreshed region from losing its bonding quality. An apparatus/method for preparing such balloons, and an apparatus/method for inflating and sealing the balloons (automatically) are also described.

Abstract: A facer for use with a plastic pipe butt fusion machine, the machine being of the type that supports two lengths of plastic pipe in spaced apart, end-to-end relationship. The facer has a housing supportable to a butt fusion machine that includes a driven gear rotatably with first and second paralleled facer plates affixed to opposed surfaces of the driven gear. Each facer plate has shapers that, when forced against the ends of plastic pipe shave off portion of the pipe so that the ends become uniform and perpendicular to the longitudinal axis of the pipe. A motor is supposed to the housing and includes a drive shaft having a drive gear that is coupled to the driven gear by a chain. An overriding clutch connects the motor drive shaft to the drive gear.

Abstract: A tire liner applier and method wherein a die and anvil shape the ends of the liner at a predetermined section which is transferred to a position adjacent the tire building drum where the section is stretched and the trailing end stitched against the drum. The leading end is clamped and applied to the drum where the next tire is built. The leading end and trailing end are tapered so that they slope away from the drum and provide a smooth transition where the ends contact the drum and outer layer of liner material. A butt splice may also be provided.

Abstract: The present invention relates to a polarization plate to a surface of a liquid crystal cell in a manufacturing process of a liquid crystal panel, where a rotary table is disposed with loading domains for the liquid crystal cell, with each domain sequentially moving to carry-in, cleaning, gluing and carry-out stations.The cleaning mechanism serves to cause an elastic plate to be pushed to the surface of the liquid crystal cell, thereby removing foreign objects.The gluing mechanism serves to cut the polarization plate on the carrier tape to a predetermined length, to thereby allow the same to be a polarization plate chip, which is in turn absorbed and supported by the glue head. The polarization chip is now torn apart from the carrier tape to thereby be glued to the surface of the liquid crystal cell.By this, process of picking up the polariation plate can be shortened and the position of the polarization plate can be determined in a state of the polarization plate being absorbed and supported by the glue head.

Abstract: When plastic tubes are melted in a connect or disconnect procedure aerosol particles are formed. The aerosol particles are confined or contained by providing an ion generator which imparts an electrical charge to the particles. The charged particles are then collected by a collector plate within the device.

Abstract: A wafer is used in a device for the selective connecting and disconnecting of plastic tubes. The wafer is in the form of a heated plate having an outwardly extending scoop on each side thereof. The wafer also includes a generally straight line horizontal slit extending through the plate from the trailing downstream edge inwardly. In order to assure single use usage of the wafer, an aperture is provided through the wafer with the aperture being covered by a sensing material. A sensor in the device will inactivate the device if the sensing material is not detected.

Abstract: A pair of plastic tubes are welded together by mounting each tube in the clamp jaws of a holder. A heated wafer is movably mounted in the gap between the tubes to cause the ends of the tubes to melt. The melted ends of the opposed tubes are pressed into contact with each other to form a welded connection. Each side of the wafer has a scoop to remove excess plastic material at the ends of the tubes to control the size of the weld connection. A pair of structural cam elements is used to create a precise spacing between each set of clamp jaws for guiding the wafer to control the plastic volume of the weld. The resulting weld is independent of rheology of plastic. The same device could also be used for disconnect purposes by cutting through a single tube and forming two tube sections. Unique double jaw construction is also disclosed.

Abstract: In a method of splicing strips of thermoplastic material to form waterstop joints, the strips are first clamped in longitudinal alignment with their adjacent ends spaced apart. While the strips are so clamped, a routing tool is used to cut complementary rebates at these adjacent ends, after which the strips are moved into end abutting relationship while the longitudinal alignment of the strips is maintained, the rebated ends being brought into a half-lap configuration. The cooperating ends are then welded together by means of an electric heating element which was inserted between the ends prior to their being clamped together.

Abstract: A method and apparatus is disclosed for bonding two pieces of thermoplastic material to one another. The method includes the steps of heating the edges of the plastic materials to be joined to at least their fusing temperatures and then forcing the heated edge portions against one another to thereby form a bonded junction. A bead is formed along at least one edge of the junction of the plastic materials as a result of the pressure of the two plastic materials bearing against one another. The welded junction is heated, optionally at elevated pressure, to at least its fusion temperature and is then rapidly cooled. The resulting weld has a high impact and dielectric strength and has a smooth overall appearance.

Abstract: Mounted in tandem on an elongated frame, a plurality of applicator head assemblies affords a versatile machine for bonding a decorative coating even to a relatively complicated pre-shaped edge of a workpiece. Means on the head for accurately positioning a rotatable applicator wheel having a circumference of silicone rubber profiled to match the edge permits the wheel to urge the coating with precision and uniformity onto the contoured edge of the substrate. An external radiant heat source raises the temperature of the silicone rubber periphery which, in turn, transfers heat by conduction to a transfer foil, thereby releasing the foil carrier and bonding the decorative film to the substrate edge. Pressure applied by the wheel in the plane of the wheel creates a wheel flat resulting in increased contact area and dwell time, thereby enhancing bonding precision and strength.

Abstract: Apparatus is described for continuously producing finger jointed lumber from individual elongated boards. Each board includes opposed end faces with elongated parallel fingers that will mate with complementary fingers of a following board to form end-jointed lumber. A reciprocating ram engages one end of successive individual boards, pushing the board longitudinally along a path to a confining box. The ram retracts to engage a successive board along its end face to push it longitudinally into engagement with the board held by the confining box. The fingers of the engaging board ends mate within the confining box and are pressed together to complete a joint. The ram includes a ram face that is complementary to the finger configuration of the board ends to mate intimately with the board end. The ram face may be heated to apply heat to the successive board ends for glue curing purposes.
