Abstract
The invention relates to a device for preparing and applying adhesive, comprising a feed unit, a preparing unit, and an application unit, wherein the feed unit is used to feed a basic component of the adhesive and/or of at least one additive, wherein the preparing unit effects continuous mixing of the basic component of the adhesive with the one or more fed additives to form the prepared adhesive and continuous conveying of the prepared adhesive, wherein the adhesive prepared in such a way is conveyed from the preparing unit into the application unit and can be applied to a workpiece by the application unit.
Claims24
A device for preparing and applying an adhesive having at least one additive, the device comprising:
- an infeed unit;
- a preparation unit;
- and
- an application unit;
- wherein the infeed unit is configured to infeed either or both of a basic component of the adhesive and the at least one additive,
- wherein the preparation unit comprises a housing bounding a mixing chamber, wherein the preparation unit has helical duct routing for introducing the basic component of the adhesive into the mixing chamber,
- wherein the preparation unit is configured to effect continuous mixing of the basic component of the adhesive and the at least one additive so as to form the adhesive,
- wherein the preparation unit is configured to continuously convey the adhesive from the preparation unit into the application unit,
- wherein the application unit is configured to apply the adhesive to a workpiece,
- wherein the basic component of the adhesive is a solid, granules, or a powder, wherein the infeed unit or the preparation unit has a heater for melting the basic component of the adhesive or the at least one additive,
- wherein the application unit has an adhesive applicator, wherein the adhesive applicator is a nozzle or an application roller,
- wherein the application unit has a reservoir configured for an intermediate storage of a defined amount of the adhesive.
A device for preparing and applying an adhesive having at least one additive, the device comprising:
- an infeed unit;
- a preparation unit;
- and
- an application unit comprises an application roller
