mÉtodo de produÇço de envoltàrios de produto, uma folha para formar um envoltàrio obtida pelo mÉtodo, e uma tira para obter a folha

Confectionery products ( 2 ) are packaged singly in double twist wraps ( 1 ) prepared from a strip ( 3 ) coated with first longitudinal bands ( 4 ) and second transverse bands ( 5 ) of adhesive, the transverse bands spaced apart to create adhesive-free zones ( 6 ) offered in direct contact to the products ( 2 ), and caused to advance along a set path (P) in a given feed direction (D). The strip is prepared with an easy tear point (A) on each second adhesive band ( 5 ), consisting of a first notch ( 7 ) extending parallel to the longitudinal axis of the strip ( 3 ) and a second notch ( 8 ) superimposed on the first notch ( 7 ); the strip ( 3 ) is then cut transversely along the second bands ( 5 ) to generate single leaves ( 11 ), each presenting an indentation ( 12 ) and a projection ( 13 ) generated by the second notch ( 8 ). The leaf ( 11 ) is folded around the product ( 2 ) to produce a hermetically sealed wrap ( 1 ) designed to tear open from the notches.
