  • Patent number: 5893958
    Abstract: In the manufacture of integrated labels it is desirable to apply pressure sensitive adhesive in a continuous manner, yet it is undesirable for active adhesive to be on one or more edges of the form since active adhesive can interfere with nip rollers upon entering a laser or other non-impact printer, or can otherwise interfere with proper operation of the printer. By using an adhesive--that is de-tackified by direct exposure to a sufficient type and dosage of electromagnetic radiation (such as a hot melt adhesive de-tackified by applying about 3000 mJ/cm.sup.2 total dosage of ultraviolet radiation)--that problem may be avoided. Apparatus for producing integrated labels with the adhesive at one or more edges being de-tackified may include a first conveyor for conveying sheets (either in stacked or single sheet form) in a first direction, and at least one ultraviolet radiation source mounted adjacent a side of the conveyor parallel to the first direction.

  • Patent number: 5891516
    Abstract: Fiber cement felts of the present invention include: a top fabric layer that includes fine machine direction yarns and fine cross machine direction yarns interwoven with the fine machine direction yarns; a bottom fabric layer underlying the top fabric layer that includes coarse machine direction yarns and coarse cross machine direction yarns interwoven with the coarse machine direction yarns; and a batt layer attached to and overlying the top fabric layer. Preferably, the top fabric layer is heat bonded to the bottom fabric layer. It is also preferred that the fiber cement felt of the present invention include a second batt layer that underlies the bottom fabric layer. In this multiple layer structure, the felt can have higher tenacity, improved resistance to blinding and compaction, and a reduced tendency to mark a fiber cement sheet during its formation.

  • Patent number: 5888339
    Abstract: An apparatus for wrapping a joint of pipe with a web of reinforced concrete includes an improved applicator that wraps the joint of pipe with a web of concrete that is reinforced with a steel mesh and which is also layered with a web of poly film. The improved applicator has a motor drive and a gear box that interfaces the motor drive with one of the belt pulleys that drives the applicator belt. The primary applicator belt can be disengaged from the pipe, thereby transferring both pulleys to idler pulleys after pipe wrapping is initiated. This allows the large motor drives that actually rotate the pipe to control the speed at which the web of concrete is applied to the pipe. The motor drive for the applicator belt is initially engaged for a few seconds to overcome initial friction associated with start up of the applicator. A timer can be used to regulate the number of seconds that the applicator motor operates until it is disengaged using the clutch.
