A method for producing a sandwich-like structure in which a pattern of particulate material is arranged between a carrier material and sprayed adhesive, said method comprising the steps of: a - providing at least one essentially flat web material as the carrier material; b - providing an essentially endless support means for said carrier material having a support pattern, said support pattern having a contact surface; c - providing a carrier material holding means; d - positioning said carrier material over said support means, whereby said carrier material contacts said support pattern with a support surface of said carrier material, and whereby the relative speed between said carrier material and the contact surface of said support means is essentially zero; e - providing a particulate material; f - providing a sandwich fixation means, wherein said sandwich fixation means is glue bonding in the form of the sprayed adhesive, the sprayed adhesive being applied after the particulate material has been transferred onto the carrier material, the sprayed adhesive being applied to a bonding area of the carrier material which is free of the particulate material and also to the particulate material, to thereby make the sandwich-like structure in which the particulate material is arranged between the carrier material and the sprayed adhesive, and wherein the method is characterized in that: g - said carrier material is supported by said support means only in the region of the support pattern of the support means; h - said carrier material is deformed by said carrier holding means such that indentations are formed in unsupported regions of said carrier material; i - an amount of said particulate material is pre-metered; j - and said pre-metered amount of said particulate material is transferred to said carrier material into said indentations thereby forming a primary pattern of particulate material. a - providing at least one essentially flat web material as the carrier material; b - providing an essentially endless support means for said carrier material having a support pattern, said support pattern having a contact surface; c - providing a carrier material holding means; d - positioning said carrier material over said support means, whereby said carrier material contacts said support pattern with a support surface of said carrier material, and whereby the relative speed between said carrier material and the contact surface of said support means is essentially zero; e - providing a particulate material; f - providing a sandwich fixation means, wherein said sandwich fixation means is glue bonding in the form of the sprayed adhesive, the sprayed adhesive being applied after the particulate material has been transferred onto the carrier material, the sprayed adhesive being applied to a bonding area of the carrier material which is free of the particulate material and also to the particulate material, to thereby make the sandwich-like structure in which the particulate material is arranged between the carrier material and the sprayed adhesive, g - said carrier material is supported by said support means only in the region of the support pattern of the support means; h - said carrier material is deformed by said carrier holding means such that indentations are formed in unsupported regions of said carrier material; i - an amount of said particulate material is pre-metered; j - and said pre-metered amount of said particulate material is transferred to said carrier material into said indentations thereby forming a primary pattern of particulate material.
