B500A/B500B Automatic Film Banding Machine

Same frame, higher rated output - The published dimensions (3000 x 900 x 1800 mm), weight (1000 kg) and installed power (220 V, 5 kW) match the 30-40 bundles/min machine in the same series, while rated output rises to 40-50 bundles/min. The extra cycles have to come from cycle time and collating sequence rather than a larger frame, so sealing dwell and the film tension window are the parameters to challenge during a factory trial.

Explicit air pressure lower limit - This is the only page in the group that prints the air requirement as ≥0.6 MPa instead of the ambiguous 'N0.6 MPa'. At 40-50 bundles/min the sealing and clamping strokes repeat more often, so holding a stable supply at or above that floor matters more here than on slower models.

Twin-reel changeover at full rate - With two independently fed film reels, a 40-50 bundles/min schedule shortens the interval between reel changes. Reel diameter, splice policy and whether the line stops for a change are the practical constraints on sustained output, and none are given in the published data.

Two model suffixes, one data sheet - B500A and B500B share one title, one description and one specification table on the source page. Any difference in collating lanes, pack pattern, discharge or control package is not stated, so the suffix must be resolved with the supplier before a purchase specification is written.

Adjustable band tension at a higher cycle rate - Bundle tightness remains adjustable; at 40-50 bundles/min the collated stack spends less time held in the sealing station, so the tension setting has to hold the stack during transfer as well as in the finished pack. Trial settings for light or overfilled cartons should be agreed before acceptance.
