Hans H Meyer's rotating paper clamp.
Hans H Meyer GMBH has just released a new generation of continuous rotating paper clamps, generation F rotating swing arm clamps.
The new generation of paper clamps is different because improved kinematics for higher clamp force on lower pressure levels allow fine adjustment of clamp force and pressure for different roll diameters and paper types, Meyer's sales & marketing director Thomas Auringer said.
"The new generation F paper roll clamps feature a more modular design for easier stock holding of parts. A new cylinder design includes pressure checkpoints and cartridge-type check valves, which hold pressure in the cylinders only when clamping.
"The rest of the hydraulics in the attachment is pressure-free," he said.
Swing arm clamps combine long and short arms to pick up rolls in the horizontal or vertical position. Split pads allow clamping of different diameters at the same time, a Meyer statement said.
The clamps can be used to handle paper from the manufacturer through to printing and paper converting companies, along the transport chain.
Smaller roll diameters typical in print companies can be picked up using the clamp's short (bottom) arm, positioned to achieve a smaller clamp opening.
Meyer's 360-degree continuous rotate drive allows sensitive positioning on the clamps to avoid paper damage.
