Abstract: A sealing apparatus for sealing a travelling packaging film. The sealing apparatus includes a first actuator, a second actuator, a first seal member, a second seal member, a slide rail arrangement, and a linkage coupled to the slide rail arrangement and connecting each of the first and second actuators to the first and second seal member. The first and second sealing members are actuated toward and away from each other between a disengaged position and an engaged position for sealing the travelling packaging film.

Abstract: The invention relates to a method for producing a packaging bag from a flexible film material (2) comprising the following steps: feeding of the flexible film material (2); adding an additional material (7) to the flexible film material (2) and producing at least one stiffened partial region (6) from the additional material (7), wherein the additional material (7) is hardened and forms the stiffened partial region (6). The invention further relates to a device for producing a packaging bag, comprising: a film feeding device (10) for feeding flexible film material (2) and an additional material adding device (11) for adding an additional material (7).

Abstract: A method of verifying seal quality of a packaging material includes providing packaging material, and applying a thermochromic ink to at least one portion of the packaging material. The method also includes applying heat to the at least one portion of packaging material to form a seal, and inspecting the packaging material to determine the quality of the seal.

Abstract: A pair of metal lead frames are stacked together with a plurality of solder coated semiconductor chips sandwiched between respective pairs of overlapped portions of the lead frames and the lead frame stack is then disposed within a fixture comprising spaced apart clamping means for clamping together the overlapped portions of the lead frames. Only the clamping means contact the frame stack and in thermally and electrically insulated relation therewith for minimizing heat loss from and electrical shorting of the lead frame stack to the fixture. Electrodes are tightly clamped against exposed ends of the lead stack for passing electrical current through the stack for causing electrical resistance heating of the stack and the soldering of the chips to the lead frames.
