8. Supply method for a device ( 1 ) for packaging products ( 3 ) comprising:
extending in a conveying direction ( 8 ) a belt ( 6 );
supplying a module ( 4 ) for packaging in batches ( 5 ) products ( 3 ) that are to be packaged from at least one lateral zone ( 9 ),
bringing up to the belt ( 6 ) said products ( 3 ) from an upstream station using a linear motor principle owing to which the products ( 3 ) are moved using shuttles ( 12 ) that circulate on a main rail ( 13 ) and that move the products ( 3 ), and at least one pusher ( 11 ) is independent of the shuttles ( 12 ) and acts on the products ( 3 ) to move them up to the belt ( 6 ) when the shuttles ( 12 ) have brought them into the at least one lateral zone ( 9 ), and
depositing the products ( 3 ) on the belt ( 6 ) from the side of the belt ( 6 ) from various parts of said zone that are distributed in the conveying direction ( 8 ).
9. Method according to claim 8 , wherein the deposition of products ( 3 ) on the belt ( 6 ) is done from various locations distributed longitudinally on the side of the belt ( 6 ) to contribute simultaneously in order to form several batches ( 5 ) each time from said locations.
10. Method according to claim 8 , wherein the deposition of products ( 3 ) on the belt ( 6 ) tracks the movement of said belt ( 6 ) in the conveying direction ( 8 ).
11. Method according to claim 8 , wherein several products ( 3 ) that are aligned in the conveying direction ( 8 ) are deposited on the belt ( 6 ) in a single deposition operation.
12. Method according to claim 8 , wherein the packaging module ( 4 ) handles the products ( 3 ) in the form of a batch ( 5 ) of products ( 3 ) that are arranged in columns ( 16 ) in the conveying direction ( 8 ) and in transverse rows ( 24 ), with the products ( 3 ) of the same column ( 16 ) being deposited simultaneously and the columns ( 16 ) of the same batch ( 5 ) being deposited one after the other, each time from another location that is further downstream.
