Apparatus for Wrapping Articles in Plastic Film

摘要

Apparatus for wrapping articles in film material includes a stationary frame supporting a vertically reciprocable frame which in turn supports a rotatable ring member carrying a film carriage assembly by which film is wrapped around an article during rotation of the ring member. The ring is in the form of an outwardly open channel and is supported for rotation relative to the reciprocable frame by wheels on the latter which underlie the upper flange of the channel. The web of the channel is captured between pairs of wheels mounted on the reciprocable frame, and a wheel of one of the pairs is driven to rotate the ring relative to the reciprocable frame. The reciprocable frame is elevated and lowered relative to the stationary frame by a chain drive arrangement, and the stationary and reciprocable frames have interengaging guide components at two diametrically opposed locations.
