Printing
As the Printing industry is vast and encompassing many facets of production, SKEANS offers numerous products and application solutions.
We offer solutions for the industry including Rotating Equipment, Pneumatic Automation, and Electric automation. From paper sheet feeding, to gluing, stamping, perforation, and cutting we can provide a processing solution to fit your needs. If it’s printing, folding, or stacking that you need, we have a variety of proven solutions there as well, with MAC Valves, PHD Cylinders, Colder print head fitting, and RFID readers. We know printing is primarily an automation process from start to finish, and we have what you need to do the job.
Additionally, we also offer high speed sensors and electric actuators that can support both heavy loads and precision movements.

Solutions:
Compressor Applications
Air bearings for product handling
Air bearings or air castors enable heavy products to be easily handled by literally floating heavy loads on a virtually frictionless film of air.
Paper pressing
Compressed air is used via cylinders for a variety of pressing applications.
Printing
Compressed air is used for operating printing pumps and equipment. As air is non explosive, it is safe and reliable.
Roller adjustment
Compressed air is used to precisely control the roller thickness which determines the paper thickness, essential for an efficient process.
Vacuum generation
Using compressed air and a venturi systems efficiently generates vacuum that is used in many processes such as product handling.
Blower and Vacuum Applications
Clean liquid handling
Centrifugal pumps for liquid handling, cleaning and recovering in auxiliary services / processes in pulp and paper mills.
Pre-press press post-press applications
Vacuum is required for a variety of applications in the pre-press area, including preparing images and film for scanning or exposure and for copying printing plates. There are also many applications where over-pressure is needed as well, such as for guiding plates or film in automatic systems. In classic sheet fed offset presses, vacuum and overpressure is always needed for paper handling – at the feeder to separate the sheets, to feed the single sheets to the different colour-aggregates or to guide the sheets through the machine.
All these applications need different amounts of air at different pressures. There are a variety of applications in the post-press arena. For example, side channel blowers for folding and cutting machines; pressure-vacuum pumps and individual vacuum pumps and compressors for collating and book binding machines; and radial blowers for removing waste paper.
Pulp drying
Vacuum is used throughout the forming section of a paper machine to remove water from the paper stock. In the forming section, varying levels of vacuum are applied across the flat boxes and couch rolls to remove the bulk of the water.
Pulp handling
Process centrifugal pumps to handle various paper pulp (wide impeller range to match different viscosity and density of process fluid).

Sensor solutions for hydraulic and eccentric presses
Hydraulic and eccentric presses are used for the entire spectrum of paper forming. When forming manually operated presses, it is important to reliably protect the operator against injuries. In addition to operation that is optimized for safety at work, e.g., through mandatory two-handed operation, the safety devices must be designed so that they cannot be circumvented. Their sensor and control solutions can be intelligently incorporated into the machines’ processes, reliably secure them, and render them tamperproof.
Sensor solutions for punching machines and laser-cutting machines
Punching machines and laser-cutting machines separate very quickly and precisely smaller parts from large paper rolls. When processing paper with punch presses or with laser cutting, safety at work plays an important role, as work is performed with high pressure and high-energy laser beams. In addition, the sensor system used must be able to detect very small stamping parts to ensure a fault-free production process. Their sensor solutions reliably and flexibly safeguard endangered areas and minimize the influence on the workflows. Moreover, sensors check for tool availability, prevent collisions, and monitor the ejection.
Sensor solutions for sheet feeders
Using sheet feeders, the paper roll is unwound from a coil and is fed to a cutting machine or press. At the start of the unrolling process, the material must be quickly and unambiguously identified. During the unrolling process, the paper must then be inspected for uniform unrolling to ensure precise further processing during cutting. At the end of a paper coil, it must be changed as quickly as possible, so that downtime can be kept to a minimum. Our switching sensors reliably detect the end of the coil and, by means of loop and edge control, our measuring sensors enable a smooth process sequence when feeding in sheet metal.
