Abstract: Apparatus for lining an irrigation canal with a sheet of fiber-reinforced plastic includes structure for depositing a layer of resin and fiber on a web of flexible carrier material, partially curing the resin prior to laying the sheet in the canal, and then laying the sheet in the canal while the resin is flexible enough to conform to the shape of the canal. The final curing of the resin takes place after the sheet is placed in the canal. A predetermined-shape wrinkle is induced in the carrier web before it is laid into the canal to assist in conforming the sheet to the canal shape without causing randomly placed wrinkles so that the sheet is smooth in the canal. The apparatus forms the sheet and is propelled so that it travels along the length of the canal, fabricating a continuous sheet as it travels. In one embodiment the carrier is a flexible but nonelastic material like kraft paper, coated on one side with wax or other film to prevent saturation by the resin.

Abstract: A truck having a road oil spreader is equipped with an apparatus for simultaneous application of oil and paving fabric to the road surface.

Venting grooves extend from the feed channels to the nozzle exit to prevent clogging of the feed channels by the tape.

Abstract: An apparatus and method for applying cellulose fiber insulation of the spray on loose fill type. The insulation is coated by a dry and thus deactivated adhesive and is stored in a storage tank. At the moment it exits the storage tanks, the insulation is exposed to and moistened by water sprayed by a nozzle member. The moistened insulation travels the length of a blow hose to reach the application site at the discharge end of the blow tube. The moisture activates the dry adhesive as the insulation travels through the hose, and the turbulence within the hose ensures that all of the fibers are moistened. Thus, by the time the adhesive is discharged by the blow tube, it sets in the absence of dust and virtually no setting time is required because the activated adhesive has begun to set.
