  • PATENTED SEP 2 4 I974 SHEET 5 BF 6 METHOD OF SECURING FITTINGS OR PLATES ONTO CONTAINERS OR CONTAINER PORTIONS AND A MACHINE FOR CARRYING OUT THE METHOD
  • This invention is related to a method of securing fittings or plates onto containers, for example cases, packings, goods, transport containers or the like or onto parts composing such containers: the method comprising the steps of feeding, in a manner known per se, a strip from a supply; imparting in the strip, by stamping, the plates with the plates having securing tabs which are drivable into the walls of the containers or container portions, and severing the strip while forming a plate of suitable length.
  • the strip is severed, after the stamping and formation of other work functions in a machine particularly designed for the purpose, into plates of a predetermined length, whereupon the plates are collected and stored to be later applied onto the containers or container portions in another plant or machine.
  • This method has however disadvantages, primarily in that the plates must be transported from one machine to another before application on the containers. This has caused increased transport and handling costs and a need for excessively large plant spaces.
  • An object of this invention is to remove the abovementioned disadvantages by a method which is characterized in that the plate is pressed onto the container portions following, preferably immediately following, the method step in which the strip is severedyThe plates will thus be directly applied from the strip to the containers thereby eliminating the need for transportation of the plates between different plants or machines.
  • An additional object of invention is to provide a machine for carrying out the method.

It is thus possible to adjust the number of stamp holders according to different lengths of the plates produced in the machine.
