Both gross weigh and net weigh bagging scales that fill open mouth bags have a spout where the product is discharged into a bag. To hold the bag on the spout while it is being filling, bagging scales offer different types of bag clamping assembles. There are two typical types of bag clamping assemblies: clam shell and center grip.
CLAM SHELL BAG CLAMPS
Clam shell assemblies have a spout with two plates that expand after the bag is spouted to hold the bag in place. Often the clam shell assembly has an adhesive or a rubber strip to help hold the bag in place. The clam shell clamps can be activated either mechanically or pneumatically with a wand or foot switch. A bag filler with clam shell bag clamps can clamp only one size bag, has a faster bagging rate, but is more expensive.
CENTER GRIP BAG CLAMPS
Center grip assemblies have two curved bands that clamp the spouted bag to the chute. A bag filler with a center grip assembly can handle a limited range of bag sizes and is typically less expensive. Center grip assemblies can be activated either mechanically or pneumatically with a wand or foot switch.
For dust tight requirements, center grip assemblies are available with fabric or leather straps that fully enclose the bag top.
Both clam shell assemblies and center grip bag clamps are offered in mild steel, stainless steel contact surfaces and all stainless varieties.
