Abstract: A system for sealing thermoplastic film includes one or more bag sealing units, each comprising a lower vacuum platen and a vacuum chamber cover adapted for sealing engagement on the platen to form a vacuum chamber. A sealing bar assembly includes a sealing bar designed for constant heated operation and a pair of cooling plates which function as heat sinks. The sealing bar assembly is pneumatically reciprocated between a raised, disengaged position and a lowered position with the sealing bar engaging the neck of a bag for hermetically sealing same. The cooling plates clamp the bag neck against a sealing support assembly. A method of sealing a thermoplastic film bag includes the steps of placing a packaging object in a thermoplastic bag and placing the bag on a cradle with the bag neck extending over a bag support assembly. A vacuum chamber cover is placed on the platen and evacuated to form a vacuum chamber. A sealing bar assembly melds the thermoplastic to form a sealed area across the bag neck.

Abstract: An envelope stripping apparatus is disclosed for opening and holding open the flaps of envelopes or mail processed in a mailing machine or other envelope-processing machine. The flaps of the envelopes are held down against a vacuum plenum during transport of the envelope. The envelopes are fed along the feeding path towards a moistening device while the flap is stripped and held by the vacuum plenum. An arrangement of the plenum apertures is such that stiffer portions of the flaps have more vacuum applied than those that are of lesser area, or at the extreme end of the flap. A second arrangement of the envelope flaps will cause additional holding of the end of the flap if it is a larger envelope with a greater area at the end such as a square flap.

Abstract: A safety catch device of a sealing machine has a baffle and a probe set. The baffle is pivotally arranged at the opening of the machine body. A conducting sheet is provided at the rear side of the baffle. The probe set has a first probe and a second probe, which are connected to a circuit unit with signal cables. The front end of the first probe exceeds the front end of the second probe by a certain distance. The front end of the first probe contacts the conducting sheet. The front end of the second probe keeps a certain distance from the conducting sheet. When the baffle swings backwards, the conducting sheet contacts the front end of the second probe to transfer signals to the circuit unit for stopping the film sealing operation. The safety of operation can thus be greatly enhanced to effectively avoid occurrence of hazards.

Abstract: An apparatus for closing a slider-operated zipper on a moving filled package, comprising means for performing the following steps: conveying a package forward in a straight line; guiding a slider on a zippered portion of the package through a channel as the package moves forward; blocking forward movement of the slider at a predetermined position inside the channel as the package continues to move forward; and releasing the slider when the force being exerted by the slider in the forward direction reaches a level substantially equal to a predetermined threshold. This apparatus can be employed in association with a continuous band sealing apparatus. The means for blocking forward movement of the slider at a predetermined position inside the channel are a pair of spring-loaded plungers, e.g., ball plungers. If the slider end stop is weak, the slider will be pulled off the advancing package and will fall onto an ejection ramp.

Abstract: Waste disposal device including a housing defining a waste compartment for receiving enclosed waste and arranged to removably receive a cartridge containing a length of flexible tubing which operatively receives waste therein, a retention mechanism for holding a quantity of waste received in the tubing and a rotation mechanism for rotating the retention mechanism when the quantity of waste is held thereby and while the cartridge is stationary in order to twist the tubing and enclose the held quantity of waste. The compartment in the housing receives the enclosed waste. The waste is thus rotated while the cartridge is held against rotation thereby enabling the formation of the twist above the waste to enclose or encapsulate the waste. A pushing mechanism may be provided on a cover of the device to push the waste into engagement with the retention mechanism.
