Apparatus for trimming printed products on at least two borders
First Claim
1. An apparatus for trimming products on at least two side borders, said apparatus comprising a first and a second processing drum positioned adjacent one another which are rotated about respective horizontal axes, said drums each comprising, respectively, first and second radially positioned receiving compartments to receive the products to be trimmed, said compartments being separated from one another by compartment walls and within which are arranged a clamping mechanism for clamping the products firmly while being trimmed wherein said first compartments of said first processing drum each comprise an open end along a circumferential surface of said first processing drum and on at least one end side, each of said first compartments comprising a first co-rotating cutting element positioned to interact with a first stationary cutting element to trim a side border of the product located in each of said first compartments, wherein said second compartments of said second processing drum comprise an open end along a circumferential surface of said second processing drum and each of said second compartments comprises a second co-rotating cutting element which is arranged at a circumference of the second processing drum and interacts with a second stationary cutting element to trim another side border of the product located in each of said second compartments, said apparatus further comprising a conveying arrangement between the two processing drums for transporting the products which have been trimmed in one processing drum into the compartments of the other processing drum.

Abstract
An apparatus for trimming multiple-sheet, folded printed products utilizing two processing drums adjacently arranged. The drums are each rotated about a horizontal axis by a drive mechanism. Each processing drum comprises radial compartments for receiving the printed products to be trimmed. Arranged on each end side of the first processing drum are two stationary cutting elements, one of which is in the operative position. The cutting element interacts with cutting elements which are fastened on the end side of the compartments on the compartment walls. In the first processing drum, the printed products are trimmed on their side borders running at right angles to the folding edge. Arranged on the circumferential edge of the second processing drum are stationary cutting elements with a cutting element in an operative position to interact with cutting elements which are assigned to the individual compartments and are arranged circumferentially in the compartments. The trimming of the open side edge, located opposite the folding edge of the printed products, takes place in the second processing drum. The transfer of the printed products which have been trimmed in the first drum to the second processing drum takes place by means of a conveying arrangement which comprises grippers arranged at regular intervals on a circulating drawing member.
