Abstract: An arrangement for ordering and binding an elongated object, in particular a cable tree (4), comprises an ordering device (1) for example a laying board with supports for a cable tree, which determines the position of the object. It also comprises a binding device which binds the object with a tape (16). To this end, the binding device has a wrapping guide (2, 3) which wraps the tape around the object (4) and a sealing device (5) with a device (17) for joining the ends of the tape. The sealing device (5) can be moved relative to the ordering device (1) so that it can be placed at the various binding sites (18) in the object (4). According to the invention, at least part of the wrapping guide (2, 3, 20, 30) is arranged on the ordering device (1), i.e., at each of the binding sites (18). The sealing device (5) is therefore not attached to the binding device until it is placed on one of the wrapping guides (2, 3, 20, 30).

Abstract: A porous web material for making infusion packages having enhanced mechanical seam integrity is obtained by treating the entire fibrous web material with an aqueous emulsion of a hydrophobic agent selected from the group consisting of high molecular weight cross-linked acrylic polymers, silicones, fluorohydrocarbons, paraffins, alkyl ketene dimers and stearylated materials. The hydrophobic agent, which may also act as a strength imparting binder, is preferably applied as a saturating treatment. The treated web is subsequently dried to insolublize the agent on the web. The web exhibits no appreciable water climb when measured using water at a temperature of about 100.degree. C. and no substantial loss of infusion characteristics while providing less than 10 percent failure in a mechanical seam therein when exposed to boiling water.

Abstract: A porous fibrous sheet material for use in the manufacture of food casings and the like is pressed prior to bonding and is bonded with about 10% by weight or less of a non-viscose bonding agent. The pressed and bonded material can be used to form casings having characteristics of thinness and elasticity similar to the thinness and elasticity of viscose-bonded casings, without the environmental problems associated therewith. The non-viscose bonding agent will result in significantly less shrinkage in the base web than results from viscose bonding.
