A METHOD OF AND A SELECTIVE STRIP COATING APPARATUS FOR APPLYING A COATING TO ONE FACE OF A SELECTED FIRST SUB-GROUP OF PARALLEL STRIPS

A plurality of parallel strips (10， 11) is passed through a coating nip between a coater (4) and a support bar or rotary roll(20) for coating one face of some (10) of the strips with an adhesive. The support bar or rotary roll (20) has circumferentially extending alternating ridge surfaces (203) and grooves(204). The strips (10) to be coated are carried by the ridge surfaces(203)， while the strips (11) to remain uncoated are located in the grooves (204) out of contact with the coater(4). Preferably， the ridge surfaces (203) and the grooves (203) are arranged in a pattern(207)， and two or more support bars or rotary rolls(20， 21， 22) may be arranged in a rotary magazine (2) for easy change to a support bar or rotary roll (20) having a different pattern (207). A plurality of coated strips (10) together with one uncoated strip (11) form a strip cluster (121)， which is pressed to form a rod or lath.
