PAPER CUTTERS -- Cutting No Corners

August 2002

"We are selling more peripherals to help with productivity and ergonomics. These include stacklifts, joggers, loaders and unloaders," confirms Brett Stowe, managing director of Perfecta-USA. "We have had more customers asking about our swivel backgauge. This allows them to swivel the backgauge via the computer for out-of-square printed sheets."

Adams, of MAN Roland, distributor of Wohlenberg cutters, informs that units can be ordered with a standard front loading knife change device, automatic waste removal system and an auto clamp stop function that allows the clamp to move just a fraction of an inch off the stock after making the cut.

"The backgauge then moves forward and positions the stock for the next cut, and the clamp goes down for full pressure and makes the next cut," he explains. "The idea is that because the clamp does not have to travel the total distance back to the top of the knife beam, it actually increases the cutting cycle speed of the cutter."

Seeking Automation

Automation and programming are part of an industry-wide trend to simplify setup and operation of finishing equipment, says Don Dubuque, product manager for Standard Finishing Systems.

"This has been influenced by heavy turnover in shops, which leads companies to want faster operator training and the ability to cross-train easily," he observes. "We see fewer equipment specialists dedicated to one piece of equipment, so owners want operators who are cross-trained on different pieces of equipment."

Dubuque feels this is made easier with the advent of simple, yet powerful, programming and automation features. Equipment decision makers are looking for equipment which is simplified through the use of control panels and touchscreens that are similar—from one piece of finishing equipment to another.

Also, the industry trend towards on-demand jobs and declining run lengths is effecting the paper cutting market.

"Shorter runs have less tolerance for waste, and this is particularly important when a job reaches the cutter because it has already been through many other production areas," Dubuque asserts. "With this in mind, any mistake in the cutting (stage) can be very costly, which leads to the absolute importance of highly accurate, precision-engineered cutting. Also, as run lengths decline, setup time becomes a larger percentage of total job time, which drives up the labor cost on the job."

Speaking of costs, Marr, of Colter & Peterson, points out that prices on equipment like paper cutting machines are actually coming down, since manufacturing has become internationalized.

"In the past, paper cutters were manufactured in one country—with all components being sourced from within that country," he explains. "In today's competitive market, this is no longer happening. Recently, our market has experienced deflation as prices have dropped."

As an example, Marr says that a few years ago the price for a new, 45˝ paper cutter was around $75,000. Today, that figure is in the $60,000 range.

"The solution, from a manufacturing standpoint, is to use various components produced in "high-tech" countries, while having castings made—and most labor-intensive assembly work done—in countries where those processes cost less," he confides.

Making the Cut

The BaumCut 26.4 programmable paper cutter from Baum Corp. is fully hydraulic and stores 99 programs with 6,464 cut steps. Features infrared safety beams, two-hand timed cut release, covered rear table, built-in table light and optical cut line indicator.

MAN Roland's latest offering is the Wohlenberg/Baumann Curve Gripper System. It will allow a customer to prepare a total of five lifts that have been jogged, aerated and counted in a small work area with either one or two operators. The pre-jogged lifts are brought to the operator via the curve gripper so that the operator will spend less time handling the stock and more time cutting, thereby maximizing productivity. This system is said to increase productivity by up to 40 percent over a conventional cutting system.
