摘要

#CMT# #/CMT# The machine has a foil transporting device i.e. guiding chain, guiding a foil web (3) in a transport direction for manufacturing of a package (4) filled with a product (2) to be packaged. A weighing device (6) weighs contents of the packages, and support plates (17, 18) are provided for partial expansion of foils at a region of the weighing device. The support plates are provided transverse direction, and transverse slots are provided in the slots. A clamping and/or expansion unit is provided for influencing clamping transverse to the transport direction of the foil in the transporting device. #CMT# : #/CMT# An independent claim is also included for a method for packing a product to be packaged. #CMT#USE : #/CMT# Machine for packaging of a product. #CMT#ADVANTAGE : #/CMT# The support plates are provided for partial expansion of the foils at the region of the weighing device, so that the weighing result can massively reduce distorted tensile stress of foil webs during the detection of weight of a package content, thus improving the determination of the weight to be weighed of the product, and hence providing the packaging machine with improved weighing characteristics. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a weighing device. 2 : Product 3 : Foil web 4 : Package 6 : Weighing device 17, 18 : Support plates.
