摘要

A multi-row wrapping machine for wrapping products (P) comprising a plurality of wrapping lines or rows (F), adjacent and coplanar to each other, each wrapping row being defined between a common input station (2) and a respective output station (3) for wrapped products, the rows developing parallel to each other along a direction of advance from the input station towards the output station, conveying means (N) being provided to convey the products (P), one in line with the other, along each respective wrapping line, the products being fed to the input station (2) in ranks at a set rate, each product of each rank engaging with each respective wrapping line at the same time. The machine has dragging means provided on each respective wrapping row to drag a respective wrapping film (T) in an unwinding direction, wrapping means to wrap the individual product (P) in wrapping film (T) and also to cut and weld the reciprocally superimposed edges of the wrapper, feeding the wrapped product to the output station (3). In each wrapping row (F1, F2, . . . Fn) of the plurality of rows there are separate and distinct means (N1, N2, . . . Nn) to convey the products (P) from the input station (2) to the output station (3), separate and distinct means to feed the respective wrapping film (T) and separate and distinct means to wrap the product (P), so that the entire product moving and wrapping stage, from the input station (2) to the output station (3) is operated and controlled along each row (F1, F2, . . . Fn) independently of the other respective rows.
