Problems solved by technology
This kind of crease is not beautiful, and it will also affect the ease of distribution at a certain time
Actual damage to the tissue may accumulate during the production process and eventually lead to machine failure
Compression between static plates in batch processing can alleviate some of the problems, but at the expense of efficiency due to the difficulty of integrating into high-speed production lines

Embodiment Construction
[0053] figure 1 is a schematic side view of the output section of a conventional tissue converting machine 1 that may be used in accordance with the present invention. In this example, the converting machine 1 was used to produce two plies of crepe paper 10 according to SCA Product Number 140299, each ply being 18 gsm. However, the skilled artisan will appreciate that any other suitable tissue may also be used.
[0054] The converting machine 1 provides as its output two webs 11 , 12 of tissue paper 10 which pass around output rolls 3 , 4 , are partially cut to define individual tissue lengths and are folded together at a folder 6 . The tissues 10 from the respective webs 11, 12 are folded together in a Z-shape as is well known in the art, with the folds of the individual webs 11, 12 being interleaved. The partial cuts are offset from each other in the respective webs so that the folded tissue webs are continuous and the tissues from each web will be dispensed alternately wh...

Abstract
A method and apparatus for compressing an elongated stack of folded absorbent tissues to form a tissue stock is disclosed. The stack of folded absorbent tissues is transported from the input end to the output end along a compression path defined between opposing first and second transport surfaces disposed on first and second compression members. The first compression member moves from the first interval to the second compression member to the second interval to compress the stack and form a log, wherein the length of the compression path is greater than the stack length, and during compression the stack moves along the compression path relative to the compression member. During this process the stack will be compressed from a first height to a second height corresponding to the second spacing.
Description
technical field [0001] The present invention relates to a method of processing tissue, and in particular to a type of tissue provided in a stack of folded individual tissues for use in a dispenser. In particular, the present disclosure relates to a method and apparatus for compressing such an elongated stack of tissue paper to form a compressed tissue paper stock. Background technique [0002] A stack of absorbent tissue material is used to provide a web to a user for wiping, drying and / or cleaning purposes. Typically, stacks of tissue material are designed for introduction into a dispenser, which facilitates feeding the tissue material to the end user. Furthermore, stacking provides a convenient form for transporting folded tissue material. To this end, the stack is usually provided with packaging to maintain and protect the stack during its transport and storage. [0003] Accordingly, a package comprising a stack of tissue paper material and corresponding packaging is p...
