Patent ID: 10160558

Abstract:
A selectively reconfigurable wrapping machine [A] for sequentially wrapping upright products. An infeed conveyor carries products to a wrapping station module where a tube of shrink-wrap material, pulled from rolled storage [B], is formed about the products by a film directing and tracking module generally designated [C] by use of a film plow [D]. Marginal edges of the shrink-wrap material are joined by a selectively configurable bottom seal module [E] which pulls the tube in to form a selectively positionable longitudinal bottom seal. A film sealing and cutting module [G] has opposed sealing heads [G2L, G2R] carried to face each other with fixed angular orientation such that the heads travel with products in the tube for a distance as it moves giving sealing dwell time for nonstop operation. A microprocessor-driven control system provides user setup controls.
