Patent number: 11981465Abstract: A method and apparatus are disclosed for processing structured tissue material to form a compressed bundle of folded tissues. A web of at least one ply of structured tissue is subjected to a destructuring operation before folding with itself or with another similar web to form a stack. The stack can then be compressed to form the compressed bundle at a pressure that is less than would have been the case, had the structured tissue not first been destructured.Type: GrantFiled: May 15, 2018Date of Patent: May 14, 2024Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAInventors: Hans Wallenius, Ingela Ljusegren

Patent number: 11247794Abstract: A method is disclosed for forming a tissue bundle from a stack of folded absorbent tissues. The method includes the steps of forming a stack of folded absorbent tissues; compressing the stack to an initial density in a first compression step; wrapping the stack a first time in a supporting wrapper to form an initial bundle and maintain the initial density; subsequently applying a second compression step to compress the stack to a final density that is higher than the initial density; and wrapping the stack a second time to form a final bundle and to maintain the final density.Type: GrantFiled: December 20, 2016Date of Patent: February 15, 2022Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAGInventors: Hans Wallenius, Björn Larsson

Patent number: 10875705Abstract: A transport package including a compressible packaging and a packing configuration, the packing configuration including at least three individual stacks of absorbent tissue paper material, and the packaging maintaining said individual stacks in the packing configuration, the transport package forming a rectangular parallelepiped delimited by six outer surfaces, defining three transport package extensions extending along three perpendicular dimensions in space defining a length, a width, and a height of the transport package. A relative deformation of the transport package is defined for each of the three dimensions, being the relative shortening of the transport package extension along a selected dimension when the entire transport package is compressed with a deformation pressure of 15 kPa between two outer surfaces and along the selected dimension, wherein, for said transport package, the relative deformation along at least two out of the three dimensions is less than 10%.Type: GrantFiled: December 18, 2015Date of Patent: December 29, 2020Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAGInventors: Hans Wallenius, Fredrik Welander
