Abstract: 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 a load during rotation of the ring member. The ring member is a cast composite ring of a thermosetting, fiberglass reinforced polyester and comprises a flange by which the ring member is supported for rotation, and a body portion on which the film carriage and slip ring members are mounted.

Abstract: A method of packaging a load that is generally prismatic in shape in which at least one rigid protective angle strip is initially placed on at least one edge of the load. The strip is then rigidly and permanently secured to the load. An apparatus is used for grasping, displacing, depositing, and holding the protective angle strip. A protective angle strip is taken from a magazine to an edge of the load by using the apparatus, wherein the protective angle strip is held temporarily while the angle strip is simultaneously secured rigidly to the load, and once it has been rigidly secured, the apparatus is disengaged from the angle strip.

Abstract: 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.
