An apparatus includes a fixed assembly and a reciprocating assembly. The fixed assembly includes a hopper, a first gas manifold, and a dispensing chamber, and the reciprocating assembly includes a channel assembly defining a channel conduit, a shield plate vertically aligned therewith, and a second gas manifold. The reciprocating assembly may move, in relation to the fixed assembly, to a first position to enable the channel conduit to be filled with bulk compressible material from the hopper, a second position to enable compressible material to be pushed from the channel conduit to the dispensing conduit and to be compressed in the dispensing chamber according to a first gas directed through the channel conduit by the first gas manifold, and a third position to enable the compressed material to be pushed out of the dispensing conduit according to a second gas directed through the dispensing conduit by the second gas manifold.

A sealing tool for forming a joint in a seal positioned on overlying courses of strap includes a body, a motor and drive train housed, at least in part, in the body, a power supply and a sealing assembly mounted to the body. The sealing assembly is operably coupled to the motor. The sealing assembly includes at least one jaw having a pair of opposing jaw elements. Each jaw element has two edges for cutting into the seal and the courses of strap and forming a bent tab. The jaw element edges are configured to cut into the seal and the courses of strap material at different distances into a width of the seal and strap material. A method for forming seal and a seal formed by the tool and method are disclosed.

A system for manufacturing tamper evident packaging, for example a bag with a tamper evident seal, includes a noncontact sealing device, a manufacturing conveyor, and in some implementations, a tensioning device and a closure device. The manufacturing conveyor conveys the bag to opposing pairs of in-feed belts of the non-contact sealing device, wherein the belts hold opposing sides of the bag together and a laser with an outlet positioned between a first pair of the belts spot welds the bag along a specified line to fuse the opposing sides of the bag together proximate an opening of the bag. In implementations including the tensioning device and the closure device, the tensioning device draws the opposing sides of the bag together prior to the bag entering the noncontact sealing device, and the closure device applies a removably coupleable closure to the bag after the bag exits the non-contact sealing device.

An apparatus (100) for manufacturing supports (6) and/or packages (80) comprising a supplying station (1) presenting a roll support (1a) configured to receive a feed roll (2) and to rotate it around a respective unwinding axis (A) to unroll consecutive portions of plastic film (3); and a cutting station (10) configured for carrying out a cutting procedure comprising separating, from an unrolled portion of plastic film (3) coming from the feed roll (2), either a strip (4) or a plurality of distinct film sheets (5) obtained from a same strip shaped portion (400). The strip (4) or the strip shaped portion (400) have a width, measured parallel to the unwinding axis (A), and a length, measured perpendicular to the unwinding axis (A), wherein the width of said strip shaped portion (400) is larger than the length of the same strip shaped portion (400). The apparatus (100) also comprises a thermoforming station (20) receiving and thermoforming the strips (4) or the distinct film sheets (5), and/or a packaging station (30) configured for closing in a package
