Abstract

A folder, and more particularly an adjustable folder for web feed gravure presses, comprising a collect cylinder able to be set for collect runs and non-collect runs and provided with holding elements (preferably in the form of grippers) and tucking blades having actuating elements preferably in the form of follower rollers which are operated by a respective cam, whose active cam part, which is preferably in the form of a recess, is adapted to be selectively exposed and covered over by means of a covering means, which is coaxial to the cam and is provided with drive cam elements which are mounted on cam element carriers coaxial to the cam and are able to be driven. In order to achieve a high degree of adaptability as regards different types of collect operations the covering cam elements of the covering device are mounted on the cam element carrier in such a manner that they may be radially adjusted.
