A method and apparatus for filling open-top containers with a flowable semi-solid material in which the material is discharged in substantially continuous fashion to a downwardly opening nozzle. An empty container is elevated into partial telescoping relative with the nozzle and moves downwardly as it is filled. The filled container is moved crosswise of the nozzle and the vertical position of the container relative to the nozzle is controlled during movement crosswise of the nozzle to initially maintain the upper edge of the filled container below the lowre edge of the nozzle at its discharge side to shear off material at a level above the top of the container and to thereafter move the filled container upwardly sufficient to cause the trailing upper edge of the filled container to substantially wipe across the lower edge of the nozzle at the discharge side thereof.

A machine for wrapping elongated articles of the type in which the machine advances a strip of wrapping material past a loading station, folds the strip into a tube around the articles and longitudinally seals the strip as it is advanced past a longitudinal sealing station, and thereafter transversely seals the tube between the articles and severs the tube to form separate packages. There is disclosed an improved article depositing apparatus which includes stationary laterally spaced article guides arranged to laterally position the articles on the strip and movable forward and rear article guides that are movable from a rear position in which they converge downwardly at the loading station to guide and confine the article as it is dropped onto the loading station; forwardly through an intermediate position in which the forward and rear article guides tilt the article forwardly while confining the article therebetween; to a forward position in which the forward article guide is spaced from the rear article guide a distance sufficient to allow the article to drop on its side onto the strip of wrapping material. The forward and rear article guides are then moved back to their rear position to receive a succeeding article.
