A bag closure machine includes a closure track that defines a channel structured to receive a plurality of closures and to position an outermost closure of the plurality of closures in a path of a production line. A break off lever is coupled to the closure track and includes a first leg and a second leg. The first leg is structured to support the outermost closure and the second leg is structured to contact a front side of the outermost closure in response to movement of the break off lever to apply a force to the outermost closure to separate the outermost closure from the plurality of closures. The first leg extends beyond an edge of the outermost closure that defines an opening in the outermost closure for receiving a neck of a bag or beyond a center of the outermost closure to prevent premature separation of the outermost closure.
An automated bag closure machine includes a mechanical bag closure advancement assembly and a mechanical bag closure breakoff assembly, wherein operation and timing of the mechanical bag closure breakoff assembly is governed by a cam and/or a manual pull-knob. The machine may include optical sensors configured to monitor the passage of bags through the machine and a fiber optic system to monitor the passage of bag closures through the machine. The machine may be mounted to other systems in a manner that allows fully fluid movement or adjustment of its position and orientation. The machine may have remote communications functionality.
A reel assembly includes a plurality of reels coupled to a reel support device. The reels are configured to rotate relative to the reel support device to dispense materials. The reel support device includes a first plate coupled to a second plate with fasteners that are coupled to first holes in the first plate and include a fastening portion received in second holes in the second plate. The fasteners are removably coupled to the second holes, such that an operator can rotate the first plate relative to the second plate by applying a lateral force to the first plate to remove the fastening portion from the second holes. The first plate rotates until the fastening portion is secured in a successive one of the second holes. During normal operation, an elastic element in the fasteners holds the first plate in position until the force is provided by the operator.

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.

A closure strip including a plurality of closures joined together in series, wherein each closure includes a hook that overlaps with a hook of an adjacent closure to form a web with a transition portion spaced from the adjacent closures. During processing, the closures are separated at the web, wherein the geometries of the overlapping hooks minimizes the bending load of the web, thus creating a high stress state that eliminates areas of compression to result in a clean break of the web without producing residue or a jagged edge on the side of the closure.
