Abstract (en)
[origin: WO9100216A1] The process relates to the production of a product consisting of a base (20) to which an adhesive (2-10) with long-term effect and a protective band (15) are attached and which allows use of the adhesive (2-10) to be deferred. The process is characterised by the use of a base (20), to one surface of which (22) the adhesive (2-10) is attached, said surface presenting irregularities. The adhesive (20) is heated to a temperature at which it becomes paste-like and almost liquid, and brought to at least one opening (4) situated above a plane surface (5) on which the base (20) has been placed. Said adhesive is then caused to flow at the same time that a relative movement between the base (20) and the opening (4) occurs. This results in the adhesive being deposited on the base (20) along at least one thick cord (10) notably one that is continuous. The temperature of the adhesive (2) is then lowered in order to increase its viscosity until it becomes paste-like to the point of turning solid. Pressure is applied to the paste-like adhesive (2-10) in order to cause lateral stretching and rolling of the cord (10) along its full length. Finally, at least one subsequent cutting of the product, which consists of a base (20), an adhesive strip (10) and a protection band (15), takes place.
