ABSTRACT:
A vertical cyclically working flat sack machine (1) serves to package flowable or pourable materials or objects in flat sacks to be sealed, which are formed from two foils (6, 7) with a common vertical foil plane (9). On a machine frame (2) a measurer (3) with filling means (5), a deflector (8) for the two foils (6, 7), a sealer (15), a discharge device (29), and a longitudinal and transverse cutter (30, 31) are provided from top to bottom. The sealer (15) has two symmetrically fashioned units (16, 17), each comprising a pivot spar (18, 18'), a sealer spar support (20, 20'), a sealer spar (21, 21') with a sealer drive (34), a heating plate (23, 23'), a clamping plate (24, 24') and the sealing tools (25, 25', 26, 26') mounted thereupon. The units (16, 17) each are pivotable from a position running parallel to the foil plane (9), especially separated by the length of a sealing lift, about a pivot axis (19, 19') by approximately 90.degree. into a fitting and cleaning position. The pivot axes (19, 19') for the units (16, 17) are arranged horizontally, and the sealing tools and the clamping plates (24, 24') are provided mainly above a horizontal plane connecting the pivot axes (19, 19').
