Cross-wound Spools

Cross-winding spools enable the production of extremely long narrow tapes – ideal for automated processing operations. Krückemeyer manufactures cross-winding spools with run lengths of up to approximately 30 km, tailored to the customer's application and production line.

Standard tape widths	2-25 mm
Maximum cut width	30 mm (material dependent)
Tape lengths	up to approx. 30,000 m (material dependent)
Width tolerance	+/- 0.2 mm
Length tolerance	+/-10 m

Any material that can be cut and wound into rolls can be individually cut to narrow tape widths as roll stock according to your specifications. Depending on the material, cutting widths from 2 mm are achievable. Please note: The cross-winding technique is material-dependent and can only be used up to a maximum 30 mm tape cut width.

Beyond the materials named above, in principle any material that can be cut and wound can be processed into a cross-wound roll – regardless of whether it is self-adhesive or non-adhesive.

Classic cross-wound reels	Individual dimensions & tape dimensions
Conical cross-wound reels	Symmetrically wound materials (optional with edge discs)
Bi-conical cross-wound reels	Asymmetrically wound materials
Disc rollers	Machine adhesive tapes simply wound with longer run lengths

Cross-wound reels can, in principle, be tailored to your processes based on winding material, dimensions and winding technique, and manufactured to meet your specifications.

Häufige Fragen zu Kreuzspulen

Cross-wound spools (also cross-wound reels) mean that a narrow adhesive, foam, or film tape is wound crosswise (transversely). This allows very long run lengths (several thousand meters) per spool – significantly more than with classic tape rolls. Cross-wound spools are especially advantageous when long run times with as few roll changes as possible are desired in automated production lines.

Basically all materials that can be cut and wound, adhesive or non-adhesive, can be processed as cross-wound. However, the materials must be available as roll stock (jumbo rolls).

Technical films (especially protective films)
Foams

Narrow tapes for cross-wound spools are normally cut to a width in the range of approximately 2 mm to 9 mm. Depending on the material, cutting tolerances of +/- 0.2 mm are realistic. Otherwise, the corresponding cutting tolerances are always individually dependent on material, tape width, core, winding pattern, and the desired running length or spool geometry.

Cross-wound spools are manufactured by us in your requested dimensions. Depending on the material and dimensions you require, the variants can be flexibly tailored to your application.

The main cost drivers for cross-wound reels are:

Material costs and batch size
Tape width (cut width) and desired running length per spool (several thousand meters are possible)
Spool specification - customization including processing aids
Quality and process requirements for consistently reproducible serial qualities

To ensure a fast and accurate quote, the following information is particularly helpful:

Details of the requested material
Notes regarding application & production line
Tape dimensions in cut width & roll length
Spool dimensions - winding width & maximum outer diameter
Core size (hub) in inches
Preferred unwind direction
Annual demand + call-off quantities

This mainly depends on whether the material is available and how specific the spool specification (core, winding pattern, take-off) is. We can already manufacture cross-wound spools from a single sample roll.
