Bag closing machines
4000 & 4500
The 4000A and 4500A are our low cost entry level models for users with small quantities.
This machine is therefore well suited for closing simple bags where a double chain stitch is not necessary.
Its simple and robust mechanics make it easy to repair and maintain for most users.
Normally, this machine is suspended by means of a spring balancer to facilitate the work. However, it is also possible to attach the machines to a pedestal with a foot switch to facilitate and increase production. At the same time, thanks to the height adjustment, you can reproduce a constant straight seam as often as you want, which strengthens the overall qualitative image of your products in the sale.
