Abstract:
1. A Process for feeding products of variable height and length into a continuous packaging apparatus comprising a variable speed conveyor ( 11 ) with a plurality of thrusters ( 12 ) that receives publishing products ( 13 , 13 ′, 13 ″), from a plurality of feeders ( 14 , 14 ′, 14 ″), a second adjustable pitch conveyor belt ( 21 ) where plastic or paper film ( 26 ) is fed continuously above said second conveyor belt ( 21 ) and towards a plurality of longitudinal and transversal sealing devices ( 23 ) that make finished packages ( 24 , 24 ′) of various sizes in height and length; said apparatus further characterized by a centralized computer ( 34 ) that directs the packaging process, said process comprising the steps of: varying the pitch on said second conveyor belt ( 21 ) of said products or groups of products ( 13 , 13 ′, 13 ″) fed by the conveyor ( 11 ) with thrusters ( 12 ) through continuous variation of the speed of said second conveyor belt ( 21 ), and operatively adapting the speed of said sealing devices ( 23 ) to the sizes in height and length of said products or groups of products ( 13 , 13 ′, 13 ″), said apparatus is further characterized in that in a step of passing over said products or groups of products ( 13 , 13 ′, 13 ″) between said conveyor ( 11 ) with thrusters ( 12 ) and said conveyor belt ( 21 ) the position in height of a height-adjustable feeding group ( 22 , 27 ) is varied according to the height of said products or groups of products ( 13 , 13 ′, 13 ″).
