  • Publication number: 20080000568
    Abstract: An insulation product and method of making the same are provided. The insulation product includes a mat containing randomly oriented fibers bonded by a binder, the mat having first and second major surfaces and a pair of side portions, and at least one flexible reinforcing layer bonded to the mat between the first and second major surfaces and extending along a length of said mat.

  • Patent number: 7250205
    Abstract: A backing sheet, and a system and method of manufacturing a backing sheet with stapling tabs. The system includes a roller device configured to apply an adherent material to a first side of the backing sheet continuously fed from a feed roll. The sheet is then fed to a first pair of folders configured to fold the backing sheet along the edges such that the adherent material holds the first fold in place. The sheet passes through a second pair of folders that form a second fold along the edges of the sheet by folding in the opposite direction as in the first fold. Advantageously, an applicator device is configured to apply a tacky substance, such as a starch solution, between the contacting portions of the second fold, prior to the formation of the second fold. The tacky substance maintains the second fold and prevents the stapling tab from opening during further manufacturing and packaging processes.

  • Patent number: 6983578
    Abstract: A bagging apparatus including a main portion having a tube section and a flared section with a wide opening. The apparatus preferably includes a device configured to mount the apparatus on a stationary structure, and a receptacle configured to fit over a receptacle receiving portion on an exterior surface of the tube section adjacent an opening thereof. A method is provided that allows for the insertion of an item into a receptacle using the bagging apparatus. The method includes the step of positioning a receptacle over an exterior surface of the tube section adjacent an opening thereof. The item is inserted within the flared section of the bagging apparatus via the wide opening. The item is then slid through a narrow opening of the flared section, through the tube section, and within the receptacle. The method further includes the step of aligning the item at a predetermined orientation within the receptacle.

  • Publication number: 20050166543
    Abstract: A method of making an insulation product is provided. An uncured or partially cured mat containing randomly oriented inorganic fibers and a heat curable binder agent is formed. The mat has a pair of side portions and a first and second major surfaces thereon. A nonwoven sheet is applied to the first major surface. The nonwoven sheet comprises randomly oriented glass fibers. The uncured or partially cured mat is heated with the nonwoven sheet, wherein the mat is cured to form a low density mat and the nonwoven sheet is bonded to the first major surface by the heat curable binder agent.

  • Publication number: 20050138834
    Abstract: In a first embodiment of an insulation manufacturing system and method, the system comprises a curing oven tower for heating uncured or partially cured insulation mats. The curing oven tower includes a plurality of vertical oven zones comprising heat sources through which the insulation mats are moved. In a second embodiment, a insulation manufacturing system is provided including a curing oven tower for heating uncured or partially cured insulation mats. The curing oven tower comprises a heat source and a conveyor system for moving the insulation mats both vertically and horizontally through the curing oven tower in a serpentine path.

  • Patent number: 6606839
    Abstract: A rolling apparatus including a first elongated projection, and a second elongated projection connected to a rotatably mounted shaft. The shaft is attached to a crank, motor or other device that can be used to manually or automatically rotate the shaft about an axis. A leading end of an elongated sheet of material is positioned between the elongated projections, and the elongated projections are then rotated with respect to one another about the axis of the shaft to form a rolled item. The rolled item is removed from the elongated projections by sliding the rolled item in a direction parallel to the axis. The rolled item is then inserted within an open end of a receptacle. Alternatively, the receptacle is slid over the rolled item following the rolling procedure, and prior to removal of the rolled item from the projections. Then the rolled item with the receptacle is slid smoothly off the elongated projections for further processing or sealing of the receptacle.

  • Patent number: 6432761
    Abstract: A split-gate p-channel memory cell of an EEPROM, and method of fabricating the cell, are provided. The memory cell includes a memory transistor and select transistor that share a common gate. It further includes two independent and distinct threshold voltage adjusts implanted in different portions of a channel region of a substrate of the memory cell. One of the threshold voltage adjusts is disposed in relation to the memory transistor so as to influence its threshold voltage. The other threshold voltage adjust is disposed in relation to the selected transistor so as to influence its threshold voltage. In the method of fabrication, an n-type of dopant is implanted into the substrate to form the threshold voltage adjust associated with the memory transistor and a p-type of dopant is implanted into the substrate to form the threshold voltage adjust associated with the select transistor.
