FIELD: bookbinding machines. SUBSTANCE: processing channel oriented along transportation channel is arranged over transportation channel which is open from top. Transportation channel, together with processing channel, determine the path of processing. Printed matter parts feed-in positions are arranged one after the other along processing path. Processing channel is provided with separate processing zones following each other. Passages are provided between separate processing zones through which printed matter parts in processing channel can get in transportation channel located below. Printed matter parts conveyed from one processing zone to the other, when passing between processing zones, are opened or turned over from one to other side, as need be. Depending on the structure of processing zones and arrangement of passages, inner parts in final product are in definite relative positions or one of parts is fitted into the other. EFFECT: increased freedom in assembling of printed matter. 14 cl, 31 dwg
