Claim 6

In the method of forming a plurality of tubular container bodies from a tube comprised of connected bodies having a helically wound strip of material with a repeated pattern thereon, and wherein the winding of said patterned strip creates an accumulation of pattern errors throughout the connected bodies on said tube; said method includIng severing said tube into discrete container bodies of predetermined length, each being of substantially uniform appearance irrespective of the position on said tube from which each body is severed: the improvement in said method comprising the steps of: a. severing said tube into discrete container bodies of uniform length including the step of severing said tube at the ends thereof for cutting said tube to predetermined length; b. severing therefrom a trim ring having a dimension equal to one-half the total accumulated pattern errors of said tube; c. severing said tube approximately at a point midway of the length thereof between adjacent of the repeated patterns of said strip, i. said step including severing said tube at points spaced from each other to cut a trim ring having a dimension equal to one-half the total accumulated pattern errors of said tube; d. severing said tube at points spaced from each end of said tube length by distances equal to said predetermined length and multiples thereof.

Claim 7

In the method of forming a plurality of tubular container bodies from a tube comprised of connected bodies having a helically wound strip of material with a repeated pattern thereon, and wherein the winding of said patterned strip creates an accumulation of pattern errors throughout the connected bodies on said tube; said method includIng severing said tube into discrete container bodies of predetermined length, each being of substantially uniform appearance irrespective of the position on said tube from which each body is severed: the improvement in said method comprising the steps of: a. severing said tube into discrete container bodies of uniform length including the step of severing said tube at the ends thereof for cutting said tube to predetermined length; b. severing therefrom a trim ring having a dimension equal to one-half the total accumulated pattern errors of said tube; c. severing said tube approximately at a point midway of the length thereof between adjacent of the repeated patterns of said strip, i. said step including severing said tube at points spaced from each other to cut a trim ring having a dimension equal to one-half the total accumulated pattern errors of said tube; d. severing said tube at points spaced from each end of said tube length by distances equal to said predetermined length and multiples thereof.

Claim 8
