摘要

The materials (2, 2a) have a material web fastened to an inner surface of a shuttering or a shuttering element (1) using a self-adhesive glue. The glue is applied to a rear side of the material web in a form of interspaced points and/or partial glue coat. The material web consists of rail-shaped carrier materials (3, 3a) and a channel or layer (4) made of fine pored material e.g. woven fabric or non-woven material. The channel forms a front side of the shuttering aid materials, and the carrier materials form a back side of the shuttering aid materials.
