* The 400 PRO only uses air if it has the optional thread pusher (80–90 psi, 4–6 SCFM). The double-needle and fold-over models run at 13.7 m/min by design: they sew two seams or fold the bag mouth before sewing.
The 400 series needs at least 15 cm of free bag above the product (also with crepe tape). With fold-over, at least 25 cm.
In systems with a feeder, bags must arrive at least 20 cm apart.
With the synchronized sewing package, the conveyor and the head are adjusted together by a variable frequency drive.
In the manual system, the operator guides each bag through the head. In the semi-automatic system, the operator feeds the filled bag to the bag closer, which aligns it in the head and cuts the thread automatically at the end: the closure is more even and the operator tires less on long shifts.
Equipment with a corrosion-resistant package, such as the 400 NS corrosion-resistant model or our stainless steel system, together with a stainless conveyor. Standard equipment deteriorates quickly in those environments.
When the product is fine (flour, sugar, powders) or when the bag's appearance matters. The tape seals the mouth better and leaves a clean finish.
Yes. We have a workshop and spare parts in stock in Escazú, and we order special parts direct from the factory.
