Powered Track Assembly -The head portion of the strap track is powered open during the tension cycle, to cleanly release the strap and seal joint onto the load being strapped. High Tension Capability -Allows use of heavy strap for high tension applications which require stress loading of the strap (ie. induced elasticity for heavy polyester strap), resulting in superior retained tension on the product. Heavy Duty Heater - Long life heat seal element stands up to heavy tension applications with excellent joint efficiency of the seal (up to 90%). Electrically Powered - Quiet, clean operation with electrical quick disconnect plug. High Speed Operation - Strap feed and take-up of up to 14ft./sec., (4.3 meters/sec.) results in fast cycle times allowing more production throughput.
