METHOD AND MACHINE FOR FORMING GROUPS OF PRODUCTS AND AN OVERWRAPPING ABOUT EACH GROUP

摘要

A method of forming groups (2) of products (3) and an overwrapping about each group (2), whereby individual products (3) , fed successively to a group-forming station (5), are formed into groups (2), each defined by at least two products (3) contacting each other; the groups (2) are then transferred, one at a time and together with respective sheets (14) of wrapping material, to respective pockets (12) on a wheel (10), and are fed through a number of work stations, where folding devices (26, 27) and sealing devices (28, 30) fold and stabilize each sheet (14) about the relative group (2) to form a respective overwrapped group (16).
