Tin Knocker TDP (TDC) Roll Forming Machine

Transverse Duct Connector Profile Roll Former

Comes Standard With: TDP Rolls, TDP Clip Rolls, TDP Clip Slitter & Feed
This 14 station roll former comes standard with the TDP/TDC rolls, clip rolls, and clip slitter. The slitter allows the user to quickly and easily turn scrap in to clips. Blanks are automatically slit to width and fed in to the clip rolls. The clip rolls can also be strip fed. The TDP/TDC roll former will roll sheet metal in to leak proof, sealable TDP/TDC flanges at speeds of up to 50 fpm. Start saving time and money by forming your own TDP/TDC flanges. With snap on corners you can reduce or eliminate the need for spot welding and an add on flange like Ductmate/Ward altogether. Check out the TDP/TDC Notcher that goes along with this machine.
