A packaging process in a packaging machine of groups of cans to form a package by applying a blank made of cardboard or the like, wherein each blank is flat, shear-printed or with the use of dies to generate at least two openings arranged consecutively for a group of cans comprising at least two cans aligned consecutively, wherein each blank is fed continuously from a deposit and said cans are continuously moved forwards, the process comprising the following steps: - feeding said blanks consecutively according to at least two independent paths (A,B); - feeding said groups of cans in a single further path, wherein each group of cans comprises at least two cans aligned consecutively; - withdrawing at least one pair of consecutive blanks from each of said at least two paths (A,B) by means of at least one manipulator (21,22); - depositing said at least one pair of blanks withdrawn from each of said at least two paths (A,B) on groups of cans by means of said at least one manipulator (21,22); characterized in that the process further comprises: - in said feeding step of said blanks consecutively according to at least two independent paths (A,B) - a withdrawal step by means of a manipulator or rotating sheet feeder from a deposit or loader of blanks carrying two adjacent stacks of blanks one behind the other - a step for depositing one blank at a time on an underlying conveyor for transporting individual blanks on plates; - a step for transporting said individual blanks on plates arranged consecutively to define said at least two paths (A,B) up to and/or below said at least one manipulator (21,22); - a step for withdrawing said individual blanks from said plates by means of said at least one manipulator (21, 22); and - a step for inserting each blank, deposited on a respective group of cans by means of said at least one manipulator (21,22) in said previous step, in a further subsequent step by means of pressing elements which are caused to press said openings of said blank on upper edges of said cans of said group. - feeding said blanks consecutively according to at least two independent paths (A,B); - feeding said groups of cans in a single further path, wherein each group of cans comprises at least two cans aligned consecutively; - withdrawing at least one pair of consecutive blanks from each of said at least two paths (A,B) by means of at least one manipulator (21,22); - depositing said at least one pair of blanks withdrawn from each of said at least two paths (A,B) on groups of cans by means of said at least one manipulator (21,22); characterized in that the process further comprises: - in said feeding step of said blanks consecutively according to at least two independent paths (A,B) - a withdrawal step by means of a manipulator or rotating sheet feeder from a deposit or loader of blanks carrying two adjacent stacks of blanks one behind the other - a step for depositing one blank at a time on an underlying conveyor for transporting individual blanks on plates; - a step for transporting said individual blanks on plates arranged consecutively to define said at least two paths (A,B) up to and/or below said at least one manipulator (21,22); - a step for withdrawing said individual blanks from said plates by means of said at least one manipulator (21, 22); and - a step for inserting each blank, deposited on a respective group of cans by means of said at least one manipulator (21,22) in said previous step, in a further subsequent step by means of pressing elements which are caused to press said openings of said blank on upper edges of said cans of said group. - in said feeding step of said blanks consecutively according to at least two independent paths (A,B) - a withdrawal step by means of a manipulator or rotating sheet feeder from a deposit or loader of blanks carrying two adjacent stacks of blanks one behind the other - a step for depositing one blank at a time on an underlying conveyor for transporting individual blanks on plates; - a step for transporting said individual blanks on plates arranged consecutively to define said at least two paths (A,B) up to and/or below said at least one manipulator (21,22); - a step for withdrawing said individual blanks from said plates by means of said at least one manipulator (21, 22); and - a step for inserting each blank, deposited on a respective group of cans by means of said at least one manipulator (21,22) in said previous step, in a further subsequent step by means of pressing elements which are caused to press said openings of said blank on upper edges of said cans of said group. - a withdrawal step by means of a manipulator or rotating sheet feeder from a deposit or loader of blanks carrying two adjacent stacks of blanks one behind the other - a step for depositing one blank at a time on an underlying conveyor for transporting individual blanks on plates; - a step for transporting said individual blanks on plates arranged consecutively to define said at least two paths (A,B) up to and/or below said at least one manipulator (21,22); - a step for withdrawing said individual blanks from said plates by means of said at least one manipulator (21, 22); and - a step for inserting each blank, deposited on a respective group of cans by means of said at least one manipulator (21,22) in said previous step, in a further subsequent step by means of pressing elements which are caused to press said openings of said blank on upper edges of said cans of said group.
