  • the present invention relates generally to innovations and improvements in packaging elongated articles of uniform sizeand shape, particularly, small sausages such as wieners and smokie links, in spaced parallel relationship between scalable packaging films so that the articles can be consummed one by one without having to leave one or more unused articles in unsealed conditron.
  • Apparatus and methods have heretofore been provided for packaging groups of elongated articles of uniform size and shape such as wieners and smokie links, in sideby-side touching relationship in evacuated, hermetically sealed skin-tight envelopes formed from upper and lower webs of packaging film having excellent oxygen and moisture barrier properties.
  • Apparatus and methods of this general character for packaging wieners, smokie links and the like in groups are disclosed in US. Pat. Nos. 3,083,106; 3,129,545; 3,l47,587; 3,189,505; and 3,195,288.
  • the upper and lower webs of packaging films utilized include laminates of saran film initially in the super-cooled or amorphous condition and such films are also used to advantage in practicing the present invention, it will be appreciated that the apparatus and method of the present invention are not limited to the use of packaging films formed of saran or laminates of saran in the supercooled or amorphous condition but are applicable to other packaging films which can be readily sealed around the articles to be packaged.
  • small sausages such as wieners and smokie links have been packaged in flat, side-by-side groups of five, for example, between upper and lower webs of packaging film which by use of the apparatus and method of the above-mentioned patents form evacuated, hermetically sealed envelopes or packages tightly fitting or conforming to such groups of small sausages.
  • prior packaged groups of small sausages have been adapted to be partially opened in such manner that individual sausage can be removed therefrom one at a time if desired, nevertheless, once the hermetic seal is broken in order to remove a single sausage the remaining sausages no longer have the protection that the hermetically sealed envelopes originally afforded.
  • the object of the present invention is the provision of an apparatus and method for receiving elongated articles of uniform size and shape, such as wieners or smokie links, which have been individually packaged in separate hermetically sealed envelopes formed in parallel spaced relationship between sealable upper and lower webs of packaging film and then functioning or operating to both separate or sever such articles in groups of predetermined number, e.g. five, from such sealed webs and to also partially separate the individual envelopes or packages within each group so as to leave them interconnected along lines of perforations permitting ready detachment or separation one from another.
  • predetermined number e.g. five
  • a more specific object of the invention is the provision of apparatus and method of the type described which may be located over the discharge end of the upper run of an endless chain of lower single-cavity die blocks and which apparatus and method efficiently utilize compressed air to sequentially actuate a series of projectable-retractable severing and perforating knives.
  • FIG. 1 is a side elevational view of packaging apparatus for continuously forming hermetically sealed envelopes around individual wieners or smokie links by combining upper and lower webs of packaging film with an embodiment of the present invention forming one of the functional units of the apparatus and operating to separate the individually packaged wieners or smokie links in small groups from within which individual envelopes or packages of single wieners or sausages may be readily separated;
  • FIG. 2 is a plan view of a group of five wieners or smokie links individually packaged on the apparatus of FIG. 1 in hermetically sealed evacuated film envelopes with each being readily detachable from one another;
  • FIG. 3 is a vertical sectional view on enlarged scale taken on line 3-3 of FIG. 1;
  • FIG. 4 is an enlarged fragmentary sectional view of a portion of FIG. 3;
  • FIG. 5 is an enlarged fragmentary view partly in section and partly in side elevation taken on line 5-5 of FIG. 3;
