US Classification:

1984189, 1984192

Abstract:

Apparatus for collating products into arrays, comprising: (a) an upper conveyor receiving the products at random intervals, the upper conveyor moving in a first direction, the upper conveyor establishing a first gap thereon between each product and a second gap thereon to create groups of products, the upper conveyor having a nose; (b) a lower conveyor positioned below the upper conveyor and receiving the products from the upper conveyor, the lower conveyor moving in a second direction substantially opposed to the first direction; and (c) a reverse shingling plate associated with the upper conveyor at the nose thereof and blocking product movement beyond the nose, whereby product encountering the reverse shingling plate drops onto the lower conveyor.

US Classification:

198429, 1984186, 1984602, 198600

Abstract:

Product is conveyed as a continuous stream by a meter conveyor () unto a transfer plate () and a transfer device (). The transfer device () is movable between a retracted position and an extended position extending over a sweep conveyor (). In a preferred form, the transfer device () is in the form of a thin piece of flexible material and is moved in the conveying direction from the retracted position to the extended position by engaging with the sweep conveyor () and is moved to the retracted position by being wrapped around a rotated roller (). Product is transferred from the transfer device () to the sweep conveyor () as the transfer device () moves from the extended position to the retracted position and is engaged by a metering bar () which controls the product acceleration on the sweep conveyor () to match the meter conveyor () until the product group leaves the transfer device (). With nested product, the leading edge of the transfer device () is scalloped to represent the product bottom leading edge.

US Classification:

Abstract:

A cutting apparatus cuts shrink wrap film residing in a roll. The apparatus includes a first roller pair receiving the film from the roll and carrying the film away from the roll; and without the need for a second roller pair to receive the cut sheet of film. Film snap-back is prevented by cutting the film between a shear deck with teeth and a rotating blade with teeth intermeshing with the teeth of the shear deck. A method for cutting a sheet of shrink wrap film, includes: feeding the film into a first roller pair; and cutting the film between the first roller pair and the second roller pair using a rotating knife with a number of teeth intermeshing with a shear bar with teeth.
