PULSED AIRKNIFE CONTROL FOR A VACUUM CORRUGATED FEED SUPPLY

摘要

A method of operating a vacuum corrugated belt feeder with positive air pressure separator during a feed cycle wherein the vacuum and the positi ve pressure air are controlled by a vacuum valve and a positive air pressure valve respectively, wherein the paper is taken away by a belt which is activated when a feed clutch is energized, comprising actuating the vacuum at the start of th e feed cycle and de-actuated the vacuum when the feed clutch is de-energized, and pulsing the positive air pressure separator by actuating and de-actuating th e positive air pressure separator during the feed cycle.
