Title: Consolidation of dry formed webs
IPC: D04H1/64
Filed: 1974-04-10
Abstract: 1424973 Non-woven fabric DOMTAR Ltd 10 April 1974 [16 April 1973] 15851/74 Heading D1R A continuous process for making a consolidated sheet comprises dry forming a web from fibres, prebonding the web to impart sufficient strength to the web to enable it to be pressed but without significantly impairing penetrability thereof by a binder, applying said binder to the prebonded web, pressing to distribute the binder substantially uniformly throughout said web and drying said web (if the binder is applied in a liquid medium). The prebonding may comprise calendering at 500 to 3000 lbs/linear inch using smooth rollers at 100‹C or less, preferably at room temperature, a preliminary application of part of the binder by spraying or by spraying with binder followed by calendering. A 2 to 20% by wt. aqueous solution of starch, animal glue or carboxymethyl cellulose is applied to the prebonded web by passing it down through the nip formed by the two rolls of a size press as binder solution is fed to the nip. In one embodiment a starch size is combined with the starch binder. The web takes up approximately its own weight of binder solution. The fibres may be chemically liberated wood fibres, groundwood and bleached softwood kraft fibres being exemplified. Before prebonding the web may have a moisture content of 4 to 25% by weight.

Abstract: 552,003. Feeding webs. SCHWEIZERISCHE INDUSTRIE-GES. Dec. 12, 1941, No. 16066. Convention date, Dec. 30, 1940. [Class 100 (i)] In a web-feeding device, particularly for a wrapping machine, in which the web is fed forward intermittently by a gripper 8 engaging its leading edge, the web is unwound from a supply roll 1 by a constantly driven feed roller 3 which feeds the web only when the wrap of the web round the roller exceeds a certain amount. This wrap is controlled by rollers 4, 6 on a pivoted lever 11 engaging loops in the web. While the gripper 8 is feeding, the roller 6 is lifted by the web and the roller 4 is moved to increase the wrap of the web round the rollers 3 which thus acts to feed web from the roll 2 until,when the gripper 8 ceases to feed, the increase in the loop round the roller 6 allows this roller to fall thereby decreasing the wrap of the web round the roller 3 till the feed thereby ceases.
