Abstract: A system for monitoring the percentage of stretch of a stretch wrap film in a stretch wrapping machine includes a first sensor associated with the stretch wrap roll and configured to generate a first signal as the film travels from the roll to the pre-stretch roller assembly, and a second sensor associated with the load and configured to generate a second signal as the film is wrapped around the load. A processor is operable to: a) calculate a pre-stretch length of the film based on the first signal during a time interval; b) calculate a stretched length of the film as the film is wrapped around the load on the rotating platform during the time interval; and c) calculate a percentage stretch of the film based on the pre-stretch length and said stretched length.

Abstract: The invention relates to a kitchen furniture item, comprising a cabinet part (1), on the surface of which a hob (2) is provided, and a furniture element (3) which laterally adjoins the cabinet part (1) and comprises a fixed lower cabinet (4) and a height-adjustable tabletop (5), wherein the tabletop (5) has an edge surface (6) which is perpendicular in the in-use position and which faces the cabinet part (1). Overall space can be saved in such a way that at least one suction opening (8) is provided in the edge surface (6), and a blow-out opening (12) is arranged in the lower cabinet (4), said blow-out opening being connected to the suction opening (8) via a flexible hose (11).
