Application device having refilling cassette

An application device configured for applying adhesive elements to substrates to be adhesively bonded, the application device comprising:

• a) a cassette unit comprising:
• a1) a guide assembly comprising a supply roll and a take-up roll,
• a2) a discharge region having a dispensing edge, and
• a3) a material tape comprising a multiplicity of adhesive elements having a carrier layer and an adhesive layer connected thereto, wherein the adhesive elements with the adhesive layer are disposed on a web-shaped separation material,
• wherein the cassette unit configured such that the material tape provided on the supply roll is guidable via the dispensing edge to the take-up roll such that the adhesive elements are separated from the separation material in the discharge region and discharged from the cassette unit, and
• b) a base unit comprising:
• b1) a cassette receptacle configured for receiving the cassette unit,
• b2) a conveyor element having a reduced-adhesion surface, and
• b3) an application element,
• wherein the base unit is configured to receive an adhesive element disposed on the conveyor element by the application element and to apply the adhesive element to a substrate to be adhesively bonded, and
• wherein the cassette unit is disposed in the cassette receptacle so as to be replaceable in a reversible and non-destructive manner, wherein the application device is configured such that an adhesive element, discharged from the cassette unit, with the adhesive layer is transferred to the reduced-adhesion surface of the conveyor element such that the transferred adhesive element can be received from the reduced-adhesion surface of the conveyor element by the application element and be applied to a substrate to be adhesively bonded.
