Abstract

An arrangement in a warehouse and a method for forming narrow rolls are disclosed. The narrow rolls are formed from a jumbo reel. At least two slitting machines are used for forming the narrow rolls. The jumbo reel has an axial direction when positioned on the slitting machine. The narrow rolls are transferred to the warehouse in the axial direction. The at least two slitting machines are positioned overlapping.

First claim

The invention claimed is:

1. An arrangement comprising a first slitting machine for forming first plurality of narrow rolls from a first jumbo reel, and a second slitting machine for forming second plurality of narrow rolls from a second jumbo reel, the first jumbo reel having a longitudinal axis direction when positioned on the first slitting machine, the first plurality of narrow rolls being arranged to be transferred to an inlet end of a warehouse in the longitudinal axis direction, the first slitting machine and the second slitting machine are positioned overlapping whereby seen from the inlet end of the warehouse in said longitudinal axis direction a body of the second slitting machine is behind a body of the first slitting machine,
wherein the first slitting machine has a first transfer line for transferring the narrow rolls from the first slitting machine to the inlet end of the warehouse, and
wherein the second slitting machine has a second transfer line for transferring the narrow rolls from the second slitting machine to the inlet end of the warehouse.

2. The arrangement as claimed in claim 1 , wherein the slitting machines are partly overlapping.

3. The arrangement as claimed in claim 2 , wherein the slitting machines overlap by 10-70%.

4. The arrangement as claimed in claim 1 , wherein the arrangement comprises at least one rewinder, the at least one rewinder overlapping at least one of the slitting machines.

5. The arrangement as claimed in claim 1 , wherein only two slitting machines are positioned overlapping each other.

6. A method for forming narrow rolls, the method comprising:
forming a first plurality of narrow rolls from a first jumbo reel by using a first slitting machine;
forming a second plurality of narrow rolls from a second jumbo reel by using a second slitting machine, the first jumbo reel having a longitudinal axis direction when positioned on the first slitting machine; and
transferring the narrow rolls to an inlet end of a warehouse in the longitudinal axis direction;
wherein the first slitting machine and the second slitting machine are positioned overlapping whereby seen from the inlet end of the warehouse in said longitudinal axis direction a body of the second slitting machine is behind a body of the first slitting machine,
wherein the first slitting machine has a first transfer line for transferring the narrow rolls from the first slitting machine to the inlet end of the warehouse, and
wherein the second slitting machine has a second transfer line for transferring the narrow rolls from the second slitting machine to the inlet end of the warehouse.

7. The method as claimed in claim 6 , wherein the slitting machines are positioned partly overlapping.

8. The method as claimed in claim 7 , wherein the slitting machines are positioned overlapping by 10-70%.

9. The method as claimed in claim 6 , further comprising positioning at least one rewinder overlapping at least one of the slitting machines.

10. The method as claimed in claim 6 , wherein only two slitting machines are positioned overlapping each other.

11. The method of claim 6 , comprising transferring the first plurality of narrow rolls from the first slitting machine to the first row of the warehouse by using a first carrier table such that the longitudinal axis direction of the narrow rolls is maintained, and transferring the first plurality of narrow rolls from the second slitting machine to the first row of the warehouse by using a second carrier table such that the longitudinal axis direction of the narrow rolls is maintained.

12. The method of claim 6 , wherein the unwinding direction of the first and the second plurality of narrow rolls is the same when they come out of the warehouse.

13. The method of claim 6 , comprising forming a customer stack, which comprises several narrow rolls that have different widths, and delivering the customer stack from an outlet end of the warehouse.

14. The method of claim 13 wherein the customer stack is provided on a pallet.

15. The method of claim 6 , wherein the narrow rolls are self-adhesive laminate rolls.
