초록 ▼

A method and apparatus for producing numerically correct partial stacks from individual leaves or sheets interfolded in a U-shaped or zigzag form on an interfolder. A double stream is formed from one or more streams of sheets by staggering or guiding together. This double stream is then continuously folded into zigzag form and piled up in a continuously growing stack, from which partial stacks of a specific size are separated. Gaps are formed in the streams of sheets which simplify the introduction of separating elements into the stack. For this purpose, sheets are removed from the streams of sheets and optionally placed accurately in position on successive sheets.

대표청구항 ▼

A method of producing numerically correct partial stacks of individual sheets which are of U-shape or zigzag-shape and which are interfolded so as to overlap, comprising: providing at least one continuously moving length of material; producing at least one continuously produced stream of neighboring sheets of equal length from said at least one continuously moving length of material by cross-separation or cross-perforation; providing a first produced stream and a second produced stream; said double stream being guided together and staggered, so that neighboring sheets lying opposite to one another are offset with respect to one another; forming a gap in one of the streams by removing at least one removable sheet; temporarily storing sheets which have been removed from the continuously produced stream; afterwards returning said removed sheets to the stream by placing the removed sheets on the sheets of the first produced stream or on the sheets of the second produced stream in such a way that the first neighboring and first removed sheets or the second neighboring and second removed sheets are aligned congruently with respect to one another; continuously folding said double stream in U-shape or zigzag shape; piling up said double stream in the form of a stack; dividing the stack which is continuously being formed into numerically correct partial stacks; and separating off said partial stacks from said stack by the introduction of separating elements in a separating zone of the stack.
