Roll-Kraft has released a portable hemming unit. The machine forms 180-degree hems on the edges of a flat strip of metal. Hems are found primarily on lighter-gauge material to strengthen the profile or improve safety in handling.
Typically, the hems are formed before the metal strip is introduced into the roll forming mill or another forming process. Most hems are small and can be formed in four stations.
Hemming units can be configured as nondriven (pull-through) or driven (with overriding clutch or continuous drive), mounted directly onto the existing roll former base or freestanding, with variable product widths and producing a single or double hem.
