  • Patent number: 4952267
    Abstract: The invention provides a method an apparatus for joining at least two webs or running lengths of material together by means of at least one strip of adhesive applied to at least one of the webs in such a manner that the consumption of adhesive is reduced and greater reliability is achieved. This is made possible by using an adhesive having a viscosity which is close to the viscosity of water and causing the adhesive to be acted upon by a low pressure and to be filtered prior to application to the associated web.

  • Patent number: 4658755
    Abstract: A method for in-line filtration of flowing liquids wherein composite filtering of mechanical entrapment type and of absorptive character is implemented in relative measures adapted to meet both flow rate and contaminant filtration requirements. The invention effects jointly operative steps of mechanical and absorptive oil-based contaminant removal with accommodation of desired flow rate of automotive coating liquid by a practice wherein these two filtration techniques are effected concurrently throughout a length of conduit assigned to filtering. The invention is practiced through the use of a fibrous body, comprised in first part of oil-absorptive fiber and in second part of fibrous matter substantially non-absorptive to oil contaminants, the second part fibrous matter being arranged to selectively entrap oil contaminants and prevent absorption thereof by such oil-absorptive fiber.

  • Patent number: 4339478
    Abstract: An arrangement for processing ligno-cellulose containing particles for the manufacture of wood-product plates. These have layers of oriented chips, and a chipper comminutes raw material. The fine material and dust are separated by a sifting device, and the sifted chips are provided with binder material by a gluing device. The chipper produces more chips of as great a length as possible than are required for forming of at least one cover layer of a mat. Behind the chipper, there are provided a wet-chip bunker and a dryer. The sifter separates the chips, obtained after removal of the fine material and the dust, into two fractions. The chip composition of one of these fractions, during the processing time, constantly contains chips which are as long as possible and which are more than that required for forming the mat layer. The other fraction has shorter chips obtained during chipping, and both fractions are present each in at least one bunker.

  • Patent number: 4121535
    Abstract: A method and apparatus for the handling of hot melt materials and the like for coating a web with the hot melt. Hot melt is fed from a source through a filter to a heated tank, and from the heated tank it is pumped to an extrusion head. Pumping of the hot melt from the tank to the extrusion head is accomplished solely by providing pressurized gas at slightly more than one atmosphere pressure over the hot melt in the tank. The source pressure of the hot melt is isolated from the supply pressure at the extrusion head, and the web to be coated is passed in operative relationship with the extrusion head. The hot melt is metered in a thin film flowing over heated surfaces in order to insure thermal uniformity without agitation. The level of hot melt in the tank is maintained at a predetermined level, and the extrusion head is provided at substantially the same predetermined level so that the extrusion will not overflow or drain when the pressurized gas from the tank is vented.
