Technical Resources and Reference Guides

This section includes technical product, application, and safety information you may find useful. The product manuals section is updated periodically and manuals listed may not be the latest versions but should be representative and suitable for selection of spare parts. You may call our customer service department at 800-863-3164 if you need a more current version. The loop control concepts section is intended to help you understand coil feeding line configurations and the slack loop/pit concepts. We’ve also included a link to a coil feeding calculator to assist in determining coil weights and production run time. Our Application Engineers can provide you personal assistance to configure a coil feeding system to your exact needs or assistance with upgrading an existing line with modern technology. They can help you upgrade from an air feed system to a servo feed and/or upgrade the drive and controls of an older servo feeding system.

Be sure to subscribe to our PRI RSS equipment release feeds to receive up to the minute information on our power presses, in die lubrication, conveyors, press automation, press safety, coil handling, quick die change, and press accessories.

Loop Control Concepts: Slack Loops

Purpose: Material storage to supply the feed while the unwinder /decoiler/straightener accelerates to line speed. To absorb and store material while the unwinder decelerates after the feed stops; storage requirement is based on speed and feed length-vs.-acceleration rate of the unwinder.

The amount of material stored is equal to the total slack length minus the straight line length. Storage is increased by greater depth not length. Rule of thumb: 2 to 3 times feed length in slack for best operation. Types of Slack Loops include Horizontal, Overhead and paddle.

Some newer coil feeding design concepts challenge conventional space and slack loop/pit requirements. Space saver coil feed lines are now available that incorporate an integrated reel, and powered feeder straightener combination. This design greatly reduces floor space requirements. Servo feeds integrated with pull through straighteners also offer opportunity for space savings but require careful evaluation of application parameters.
