Abstract
An elastic-applicator for applying an elastic element onto a layer of material includes a disc pair and a drive unit for driving the two discs of the disc pair, wherein the discs of the disc pair and the drive units are configured for operation with different speeds is to enable a reliable and uniform application of an elastic element onto a layer web in a most simple manner and at the same time is to be capable to apply elastic elements of different sizes or lengths and stretch coefficients especially easily and in particular without cumbersome retrofitting work. For this, at least one disc of the disc pair has a number of sheath-side circumferential suction openings.
Claims11
-10. (canceled)
An elastic-applicator for applying an elastic element onto a layer of material, comprising:
- a disc pair comprising two discs;
- and
- drive units for driving the two discs of the disc pair, wherein the discs of the disc pair and the drive units are configured for operation at different speeds, wherein at least one disc of the disc pair has a number of suction openings which circumferentially surround a sheath of the disc.
The elastic-applicator of claim 1, further comprising a cutting device.
A method for operating an elastic-applicator for applying an elastic element onto a layer of material according to one of the claims 1 to 9, comprising:
- rotating a first disc of a disc pair with a lower speed than a second disc of the disc pair;
- supplying the layer of material at a speed essentially corresponding to the speed of the first disc;
- guiding the elastic element through the disc pair, thereby stretching the elastic element, wherein the elastic material is held on the discs by a number of sheath-side circumferential suction openings;
- and
- connecting the elastic element with the layer of material.
