Abstract
A block of material from a folded web of material and a process for producing this block of material The block of material (MB) comprises a folded web of material (1), which is divided into a plurality of adjacent and coherent layers of strips (3) by means of perforation lines (2) imparted along the longitudinal direction of the web of material.
The perforated block (MB), which is precompressed in its height (H) to create standing stability, is spliced, with the same strip sides, at its trailing strip end (4a) and the leading strip end (4b) of its adjacent strip layers (3), to form. a strip (4) with identical strip sides (S) that is continuous through the entire block (MB), after which it is completely compressed in its height (HI) and packaged into a heat-sealed plastic wrap (5) that maintains the block compression, so that it forms a free-standing material block (MB).

A block of material of this type is known from DE 198 81 126 Tl. In this block, the individual, strip-shaped web sections are completely separated iato separate strips, except for the connection of the leading section ends to the nailing section ends of the adjacent sections_ As a result, the block has only a tow side stability and is very difficult to manipulate during the process of wrapping it in a wrapping cover.
it is furthermore known that, in the hygiene industry, to manufacture hygiene products, webs of material are wound onto large rolls and strips are cut from these rolls in predefined widths based on the desixed specification, and then subsequently wound onto rolls again sad delivered in this iaitu '00 DO 09:52 FAX +49 521 88043 KIRBY CD 0 003 Oc t-16-2000 10 :46am F rom-Btl'OWOy AIRD NE I IMRhCA 0 2 3 2 3 8 51 2 0 0 0 -1 226282089 ~ T-012 P. 003 F-663 form to the manufacturer of hygiene products, who then produces the end product from them. A
cost effective delivery and proc~essi~g of the fluffy materials in question is desired, however, rolls have a large shipping volume and frequently incur damage to the material, which results in relatively high costs. .
Furthermore, from US 1 985., 676, a folded web of paper is known, the adjacent, strip-shaped web sections of which are separated from one another by Ions cuts with only minute webs remaining, so that individual strip packages can be pulled off for processing.
It is the aim of the present invention to improve the above'mentioned block in its stability by means of the mutual support by the adjacent web sections, while providing for an easy unfolding of the strips.
This aim is met with the adjacent strip-shaped web sections being divided by a micro-perforation line, but coherently firxttty connected to one another in those areas, and separable along the inicro-perforation line for further processing in such a way that the individual strip-shaped web sections can be unfolded from the block, one after another and without interruption, from an unattached leading end of the web section.

This block of material, which is stable in itself is formed into a free-standing block with less work than required fox the previously known strip stacks, by means of a known precompression and finishing compression, and packaged in an inexpensive plastic wrap.
Multiple blocks of materials may advantageously be sewn together at their respective leading and trailing ends, so that a practically endless production process can be performed with many strung together material blocks that are connected to one another by sewing.

A,fteiwards the block (MB) is completely compressed tA a packaging and transportation height (Hl) and packaged in a heat-sealed plastic wrap (5) that maintains the block compression and also encompasses the honeycombed cardboard (3).
For the splicing ofthe two adjacent strips (4) at their trailing strip end (4a) and leading end (4b), the strips (4) are separated at a certain length ac their perforation connection (perfocation lines 2) between adjacent layers (3) and then placed over one another with their same strip sides (S) xnd sewn together with the overedge seam (7) .- cross seam.
In the overedge seam (7), the thread (6) is stitched through the iwo strips (4a, 4b) in one stitch (6a), ai2er which an empty stitch (6b) is performed outside the strips (4a, 4b), etc., as shown in Fig. 9, which also shows the edges (4c) ofthe strip ends (4a, 4b) cut off.
When the strip ends (4a., 46) that are lying upon one another for sewing, are folded out by 180', the butting joint (SS) of the spliced strips (4) is obtained, and the cross seam (7), according to Fig.
10 and 12.
T'he equal-sided strip splicing is a joining top side/top side ofthe strips (4) so that the structure of the individual strips (4) i5 maintained. One ofthe strip sides may be smooth, .for example, and the other one textured, the two strip sides may have different~colors or one strip side may be provided -with a film (F) - Fig. 11, 12. In their spliced condition, the strip sides (S) ste always identical and on the same side of the strip.

CA 02323851 2000-10-z02fi282089 T-012 P.009/014 F-E63 The perforated folded block (MB) has, e.g., a height (~ of approximately 1500 mm and the completely compressed block (MB) has a height (H1) of 1000 mm, with the width and depth of the block (MB) always remaining the same; and the width is approximately 840 mrn, and the depth approximately 730 mm. At this block size, the block (lv>B) has 12 strip layers, each with a width of 70 mm. The number of layers (n) may be selected differently, however, and so may the width, depth and height of the block.
The leading end (4b) of the first layer of strips (3) is guided directly into the production apparatus, ' particularly for the production of hygiene products, and the trailing strip end (4a) of the last layer of strips (3) is spliced to the leading end (4b) ofthe fast layer of strips (3) of a given further block (MB) for a continuous production, as shown in Fig. 8, practically permitting an endless production. A large number of materials may be used for the web of material (1), especially formed fabric materials; the packaging wrap (5) may be made of inexpensive plastic films, e.g., Pli bags. .. ..
Claims (6)
1. A block (MB) of a folded web of material for producing hygiene products, e.g., absorbent pads, having adjacent strip-shaped web sections (3), the trailing web section ends (4a) of which are connected to a leading web section end (4b) of the respective adjacent web section (3) with a rotation (W) by 360° that compensates for the inherent twist, with the respective leading web section end (4b) of a first web section (3) and trailing web section end (4a) of the last web section (3) kept free for an external connection, characterized in that the adjacent strip-shaped web sections (3) are each divided by a micro-perforation line (2),but connected there in a coherent firm connection, and separable along the micro-perforation line (2) for further processing in such a way that the individual strip-shaped web sections (3) can be unfolded from the block (MB),one after another and without interruption, from an unattached leading web section end (4b).
2. A block of material as defined in claim 1, characterized in that the connected trailing web section ends (4a) and leading web section ends (4b) are spliced with a medical grade thread (6), with a so-called overedge seam (7) across butting joints (SS).
3. A block of material as defined in claim 1 or 2, characterized in that the overedge seams (7) are arranged on one side of the block of material (MB) and the rotated portions (W) are aligned in the height direction (H) of the block.
4. A block of material as defined in one of the claims 1 through 3, characterized in that the black of material (MB) has a rectangular block shape.
5. A block of material as defined in one of the claims 1 through 4, characterized in that the block of material (MB) is packaged in a heat-sealed plastic wrap (5) in a height compressed form.
6. A block of material as defined in claim 5, characterized in that one each stabilizing layer (8), preferably made of honeycombed cardboard, lies underneath and an top of the block of material (MB) inside the plastic wrap (5).
