Wrapping machine
Abstract
Abstract A PACKAGE WRAPPING MACHINE HAVING ROLLS OF WRAPPING MATERIAL SUPPORTED ON A ROTATABLE SHAFT HELD AT EITHER END BY A FRAMEWORK. A PLATFORM FOR WRAPPING PACKAGES IS MOUNTED BEHIND A CLOSELY SPACED HEATED SEALING PLATE ON THE FRAMEWORK. AN ELECTRICALLY HEATED WIRE IS SUSPENDED BY TWO ROTATABLY MOUNTED BRACKETS AND POSITIONED BETWEEN THE WRAPPING PLATFORM AND THE SEALING PLATE. IN ITS RECESSED POSITION, THE HEATED WIRE IS AT A LOWER LEVEL THAN THE PLATFORM IN ORDER TO PREVENT INADVERTENT CONTACT WITH THE WIRE. DURING USE, THE HEATED WIRE IS RAISED TO A HIGHER LEVEL BY AN ACTUATOR WHICH ROTATES THE BRACKETS HOLDING IT. THE ACTUATOR MAY BE A PLATE WHICH IS MOTIVATED BY CONTACT WITH THE PACKAGE AS IT IS MOVED FROM THE WRAPPING PLATFORM TO THE HEATING PLATE. A MANUALLY OPERATED FOOT PEDAL MAY ALSO FUNCTION AS THE ACTUATOR. A SHIELD IS OPTIONAL TO FURTHER PROTECT THE HEATED WIRE IN ITS RECESSED POSITION.
