A MACHINE FOR FORMING CONTAINERS, IN PARTICULAR CONTAINERS FOR FOOD PRODUCTS

摘要

Containers ( 2 ) for food products are manufactured on a machine ( 1 ) equipped with a feed station ( 4 ) supplying a single file of tubular elements ( 2 a), a first heat sealer ( 10 ) by which a first open end ( 2 b) of each tubular element ( 2 a) is closed and secured, and a first rotary conveyor ( 3 ) capable of movement between a first operating position in which the tubular elements ( 2 a) are taken up from the feed station ( 4 ), and a second operating position in which the tubular elements ( 2 a) are offered to the first heat sealer ( 10 ). The same machine ( 1 ) is equipped with a second heat sealer ( 36 ) such as will complete the container ( 2 ) by closing and securing a second open end ( 2 c) of each tubular element ( 2 a) opposite to the first open end ( 2 b), and incorporates a second rotary conveyor ( 32 ) located between the first conveyor ( 3 ) and the second heat sealer ( 36 ), capable of movement between a first operating position in which the partly enclosed tubular elements ( 2 a) are taken up from the first conveyor ( 3 ), and a second operating position in which the tubular elements ( 2 a) are offered to the second heat sealer ( 36 ).
