Assembly containing stacks of a web of material

Abstract

The invention concerns an assembly (A) containing a plurality of stacks of strip shaped material, which is fanfolded in the stacks between a leading end (111a, 112a) in a first end of the stacks and a trailing end (121a, 122a) in a second end of the stacks, and arranged to be able to be fed out through unfolding of the material continuously at least until the assembly has been emptied. The assembly contains two such packs (1, 2) each of which contains a plurality of such stacks (101a-d, 102a-d) arranged side by side. The leading ends and the trailing ends of the strip material of the stacks of the two packs are alternately joined to one another, so that a continuous strip is achieved with a leading end (111a) of the assembly in a first stack of one of the packs and a trailing end (122d) in a last stack of the other pack. The joined strip material sections between the trailing ends of the stacks of the second pack and the leading ends of the stacks of the first pack extend between the joined strip material sections between the trailing ends of the stacks of the first pack and the leading ends of the second pack. A plurality of such assemblies (A) may be spliced to form a multi-assembly.

Description

TECNICAL FIELD

[0001] The invention concerns an assembly containing a plurality of stacks of a web of material which is fanfolded in the stacks between a leading end in a first end of the stacks and a trailing end in a second end of the stacks, and arranged to be able to be fed out by continuously unfolding the web of material at least until the assembly has been emptied. The invention also concerns the preparation of the assembly and a method for feeding out a web of material, including use of the assembly of the invention. BACKGROUND OF THE INVENTION

[0002] The invention has been developed with the primary objective to provide spliced strips intended to be included in a system for automatic manufacturing of disposable sanitary towels, napkins, and the like. In such products, layers of non-woven materials are included, which form a surface layer on the top side of the product The starting material is strips of non-woven material, which are difficult to splice between one roll of ma...

Embodiment Construction

[0026] A prototype embodiment of an assembly A according to the invention is shown in the drawing. It consists of two essentially parallelepipedic units, in this text referred to as a first pack 1 and second pack 2, the shape and size of which may be adapted to international standards for transportation. Each pack consists of a plurality (more than two; equally many in each pack) of parallel stacks abutting one another, of strip-shaped material, which is folded in a fanfold manner between the ends of the stacks. With reference to the direction of feeding the strip material from the packs, the first folds in the stacks are designated 14, while the last folds are designated 15.

[0027] The first stack of the first pack 1 is designated 101a, the second stack is designated 101b, etc. In the illustrated case, the case contains four stacks. The last stack of the first stack is designated 101d. In the second pack 2, the stacks are correspondingly designated 102a, 102b, 102c and 102d in orde...
