ABSTRACT:
A machine is disclosed which is intended to apply a saw-toothed blade to containers (for example of cardboard) which hold a coil or roller of aluminum foil or plastics material film of the kind used, for example in the kitchen or household in general. The saw-toothed blade must slightly protrude from the bottom front edge of the container to enable the user to tear out the portion of foil or plastics sheet to be used from time to time. The machine comprises a station in which the saw strips are severed from a metal tape and are applied to the flattened container, the latter being conveyed to the station by a conveyor belt assembly. The machine is equipped with appropriate cam and lever controlling and synchronizing means to have all the operative steps performed in the correct sequential order: the machine is compact and easily inspectable by one operator and the feeding means are all located on the longitudinal central axis of the machine. The station at which the metal strips are severed and applied to the cardboard sheets is placed nearly midway between the points at which the metal tape and the cardboard pieces are fed, these two materials being fed into the machine from opposite directions, that is, in counterflow relationship.
