Abrégé

A lift mechanism for simplifying the raising and lowering of a machine component has a base and a frame structure. The lift mechanism may include a lift arrangement interposed between the base and the frame structure that allows for the raising and lowering of the frame structure about a single lift point. The lift mechanism may also include various shafts, drive members, links, and arms, which in combination translate rotational movement of a motor into linear vertical motion. For instance, a drive link and an arm may be rotatably attached to one another, as well as a drive shaft and a second shaft. Additionally, a drive member may be associated with the motor. In operation, the drive member may be rotated by the motor, and a drive belt transmits rotation of the drive member to the drive shaft, the second shaft, the drive link, and the arm.

A mandrel for supporting a roll of flexible web material has a brake mounted thereto that can be selectively activated to apply a braking force to rotation of the roll of flexible material about the mandrel. The brake includes an inflatable bladder and a shoe, such that when the bladder is inflated the shoe is pushed into engagement with the core of the roll of flexible material. The mandrel is particularly well suited for use with a packaging machine in which a sheet of flexible material is indexed form the supply roll. Before the completion of an indexing cycle, the bladder may be inflated such that further advancement of the sheet of flexible material or rotation of the supply roll is countered and inhibited. This braking of the supply roll advantageously introduces tension to the sheet of flexible material without the use of a dancer roll arrangement.

A forming tool usable with a packaging machine utilizes adhesive bonds rather than weld joints or fasteners to interconnect structural components of the forming tool. Using adhesive rather than weld joints and mechanical fasteners provides smooth interfaces thereby reducing the collection of bacteria, germs and cleaning residue on the surfaces of the forming tool, which is particularly advantageous for forming tools used with packing machines used in sanitary environments, such as for food or pharmaceutical packaging.
