ADJUSTABLE FORMING COLLAR ASSEMBLY

An adjustable forming collar assembly is provided for a form, fill and seal apparatus having a forming tube about which packaging film is positioned for formation and filling of a package. The adjustable forming collar assembly includes a mounting plate positioned to extend laterally on opposite sides of the forming tube. To accommodate filling of packages of differing sizes, first and second forming segments are provided which can be adjustably positioned on the mounting plate. Each of the forming segments is shaped to guide the packaging film from a generally flat configuration to a tubular configuration extending about the forming tube. The forming segments are adjustably positionable on the mounting plate. By this arrangement, the first and second forming segments can be selectively positioned toward and away from to each other on the mounting place, and thus adjustably positioned with respect to the forming tube, to thereby selectively adjust that size of the package being formed and filled. The assembly further includes first and second rib cages which can be adjustably positioned with respect to the forming tube to further accommodate formation and filling of differently sized packages.
