Abstract

Method for arranging a series of products (17, 106) which are moving in succession in the downstream direction along a conveyor belt (2, 103, 104), in such a way that they go into phase with a processing unit connected downstream. To control an activation element for arranging the products, before a product passes the element, the first speed Vx of the products upstream and the second speed Vy downstream of the element, the position Yn of the product processing unit, and the position Z of the element are measured. The distance Xn which is covered by the detected product from the above-mentioned position is determined. The required position Za of the element (9, 113) and the required speed Vya are calculated from Vx, Vy, Xn and Yn. The measured position Z and the measured second speed Vy are compared with the required position Za and the required position Za or the measured speed Vy and the required speed Vya, the element is moved or the second speed Vy is changed.
