Abstract
A pallet stretch wrapping machine includes a turntable attached to a lower portion of a column for supporting an article to be wrapped thereon. A frame is vertically movably mounted in the column and includes an upper housing, a lower housing, and a vertical wall connecting between the upper and lower housings. A plurality of upright rollers are rotatably mounted between the upper and lower housings. An upright post is fixedly mounted on the lower housing for supporting a spool. A roll of resilient film is wrapped around the spool and extends through each of the rollers which can co-operate to deliver the roll of resilient film to envelop the article by turning the turntable. A velocity adjusting mechanism is mounted between the upper and lower housings for adjusting a rotational velocity of each of the rollers for delivering the roll of resilient film.
