  • Patent number: 4623081
    Abstract: The invention relates to a burster apparatus (44) for separating into sheets a continuous form (22) which has transverse weakened lines and which is arranged to be conveyed along a feed path (43) through the apparatus. The apparatus includes a movable burster rod (82) which extends across the feed path, and a clamp member (96) operable to clamp the continuous form (22) with a weakened line aligned with the path of movement of the burster rod. By means of cams (70) and link members (92), the rod (82) is arranged to be moved through the feed path (43) while the form (22) is clamped, the rod being inclined relative to the feed path. During this movement, the rod (82) progressively bursts the form (22) along the aligned weakened line from one edge of the form to the other, thereby effecting a reliable bursting of the form even if the weakened line is improperly formed.
