a) feeding a laminate web comprising a backing layer, a support layer, and an adhesive matrix layer arranged between the backing layer and the support layer, as input material;
b) pressing an edge area of the adhesive patch to be manufactured on the backing layer thereby pressing out adhesive matrix material under the edge area and bending the edge area around the adhesive matrix layer; and
c) cutting out the adhesive patch to be manufactured by cutting the backing layer outside the edge area.
