Abstract: A folding machine includes a first folding roll with a series of the gripper assemblies and a series of tucker assemblies uniformly and alternately spaced to interact with a series of gripper and tucker assemblies of an adjacent second folding roll. The series of alternately spaced gripper and tucker assemblies interact to grip, carry, and release material in a manner so as to generate a folded stack of material, such as sheet material. Each of the gripper assemblies generally includes a rotatable blade, a shaft configured to rotate the blade, a spacer disposed between the blade and the shaft, and a bolt coupling the blade and the spacer to the shaft. A housing is configured with seals to retain lubricated bearings to provide rotation of the shaft of the gripper assembly and to prevent contamination of the bearings.

Abstract: A folding apparatus includes a folding blade cylinder that carries at least one group of identical tools which are distributed homogeneously about the periphery of the folding blade cylinder. A cam plate is traced or followed by a control lever of each such group of tools and is usable to control a working movement of the tool. A cover disk, consisting of a plurality of cover cams, can be rotated. The cover cams of the cover disk are displaceable between an inactive position, in which they enable the control of the working movement by the cam plate, and an active position in which they prevent such movement. Two groups of tools are used on the folding blade cylinder and the cover cams form a first group of cams at an angular distance of between 60° or 120° to each other, and a second group of cams at an angular distance of between 90° to 180° to each other.
