Abstract: The adhesive dispensing product comprises a coherent piece of carrier sheet material with two opposite surfaces, one of which is a first release surface, the piece of carrier sheet material has two opposite lateral side edges. A plurality of individual adhesive segments are present on the first release surface, which adhesive segments each has a circumferential surface, and the circumferential surfaces of adjacent adhesive segments are separated by a distance of at least 0.5 mm. The adhesive segments feature a first adhesiveness relative to the first release surface allowing the adhesive segments to be dispensed from the first release surface. The adhesive dispensing product further comprises a plurality of individual pieces of cover sheet material, which cover sheet material has two opposite surfaces, one of which is a second release surface.

Abstract: A method for the production of a clay or cementitious construction unit, such as a paving block or slab, having a textured face surface, comprising contacting the intended face surface of an incompletely hardened, free-standing, self-supporting clay or cementitious construction unit (2), (3), with a water-absorbent porous membrane (6), for example of paper or other non-woven fibrous material, contacting the membrane-covered surface of the unit with the contact surface of a vibratable element (9), the contact surface of the vibratable element having a non-relief surface, or carrying a reverse image of a desired relief pattern to be applied to the face surface of the unit, vibrating the vibratable element with vibration head(s) (10), (11), (12) at a frequency greater than 14 KHz while it is in contact with the membrane-covered face surface of the unit, breaking contact between the textured face surface of the incompletely hardened unit and the membrane, and hardening the construction unit.
