Abstract
For decelerating, accelerating and/or deflecting conveyed printed products (3), pressing elements (1, 2) act on the printed products (3) with normal forces (F.sub.N). The action is carried out in a resilient manner by contact elements (4) fixed to spring elements (5) such that the time of the action on the printed product (3) is made longer. Thus an improved deceleration or acceleration effect is achieved by means of friction forces and/or a deflecting effect is achieved by means of a momentum.

A method for selectively accelerating or decelerating printed products being conveyed in a conveying direction parallel to main surfaces of the products, each of the products having two generally parallel main surfaces, the method comprising the steps of:
- providing a counter element having a contact area,
- conveying the products in a product stream past the counter element such that the contact area of the counter element is substantially parallel with one main surface of each product being conveyed past the counter element,
- providing at least one spring mounted contact element, and
- acting on a second main surface of a product being conveyed past the counter element with the at least one spring mounted contact element, the step of acting including
- abruptly moving the contact element against the second main surface of the product, thereby pressing the product with a sudden clamping force between the contact element and the contact area of the counter element, and moving the contact element substantially parallel with the conveying direction substantially maintaining the clamping force on the product between the contact element and at least part of the contact area.
A device for selectively accelerating or decelerating printed products being conveyed in a conveying direction parallel to main surfaces of the products, each of the products having two generally parallel main surfaces, comprising the combination of
- means for conveying products in a product stream in a conveying direction;
- means for mounting a counter element with a contact area facing one main surface of a product being conveyed in said stream past said counter element;
- a spring mounted contact element;
- and
- means for supporting said contact element for movement substantially parallel with said conveying direction and for abrupt movement toward said contact area, whereby said contact element moves against said product to clamp said product between said contact element and said contact area with a clamping force and moves along said conveying direction to maintain said clamping force against at least part of said contact area.
