Inventor: BAILEY THOMAS WILLIAM
IPC: B65B43/46
Filed: 1997-11-26
Abstract: The invention provides a method of and apparatus for handling objects, such as flattened bags (4') on a packaging line. An open topped container (3; 401) is carried at the top of a flanged member (9) carried by a carriage (6) which is moved by an endless chain (2) at a constant speed along a first path in a conveying direction (A) through a loading station. The container (3; 401) comprises two halves (24, 25) which are separated as the container (3; 401) moves through the loading station in order to allow a flattened bag (4'), which moves faster than the endless chain (2) along a second path which converges with the first path, to enter the container (3; 401) and the slow down to the same speed as the endless chain (2). The two halves (24, 25) then close thereby trapping the bottom seal (63) of the bag between the opposed portions (24d, 25d; 201, 202) at the bottom of the container (3; 401). Plenum chambers (47, 48) in the base of the container (3; 401) can be evacuated, as the container (3; 401) and bag (4') travel on, so as to effect evacuation of chamber which surrounds the bottom part of flattened bag (4') and is formed by the bottom walls (24d, 25d; 201, 202), the side walls (24a to 24c, 25a to 25c), and two stationary members (61, 62; 421, 422) under which the container (3; 401) is caused to pass causing the flattened bag (4') to open and conform closely to the interior of the container (3; 401).

Title: Soft tissue achieved by applying a solid hydrophilic lotion
Inventor: KRZYSIK DUANE GERARD
IPC: A61K8/02
Filed: 1998-07-29
Abstract: A superior soft tissue product, such as facial tissue, bath tissue or paper towels and the like, can be made applying, on the surface(s) of the tissue, large numbers of individual deposits of a melted hydrophilic composition comprising a high molecular weight polyethylene glycol, a fatty alcohol (C14-C30) and lipophilic emollients or solvents, including water, and thereafter resolidifying the composition to form a distribution, preferably a uniform distribution, of solid deposits on the surface(s) of the tissue. Because the composition is a solid at room temperature and rapidly solidifies after deposition, it has less tendency to penetrate and migrate into the sheet. These solid deposits are characterized by a penetration hardness of from about 5 to about 360 millimeters.
