An application unit in a packaging machine attaches a material blank to containers in a container group so as to form a multipack. At least one pressing element connect the material blank to the containers while they are conveyed along a transport plane. A drive unit moves the pressing element with a tool plate between out-of-engagement and engagement positions with the containers. The drive unit has mutually parallel and spaced-apart first and second drive disks to be rotated about respective first and second axes of rotation. The first and second axes of rotation are horizontal and located at the same height but not coaxial with each other. The pressing element is articulated to the first drive disk by a first joint axis and to the second drive disk by a second joint axis such that the tool plate is oriented horizontal during rotation of the two drive disks.

A rotary to linear actuator, comprises a drive crankarm that rotates in a first axis of rotation; a first and second gearset connected to the drive crankarm through a second crankarm; and a piston captured between the first gearset and the second gear set, wherein the first and second gearsets rotate a crankarm connected to one end of the piston, wherein the piston is caused to move linearly upon rotation of the crankarm.

The conveyor device for conveying flexible containers along a packaging line comprises a track (1) defining a horizontal closed path and one or more pairs of left and right movers (2a, 2b) movably mounted on the track (1) for moving along the path by the effect of active and reactive elements configured for independently driving and controlling the left and right movers along the path, pairs of left and right gripper arms (3a, 3b) pivotally connected to the left and right movers (2a, 2b) by respective left and right articulations (6a, 6b) about vertical axes, and one or more pairs of left and right clamps (4a, 4b) respectively mounted on the left and right gripper arms (3a, 3b) and configured for gripping one or more flexible containers (5) in a vertical position. The left and right gripper arms (3a, 3b) are linked together by a parallelism-keeping mechanism.

A fusion welding device, comprising a fusion welding work motor, a fusion welding work moving assembly, and a fusion welding work fixed assembly, the fusion welding work motor being connected to the fusion welding work moving assembly by means of a transmission mechanism. The fusion welding device is provided with a central connection component that is able to rotate, and the central connection component is provided with a first input position, a second input position, and a locking structure connection position.

A system and method of providing a secondary means for removing thermoforming trim material from a continuous-loop clamping chain (202) having clamps (302) biased to engage a clamp grip surface (314). A cam (400), attached to a sprocket located downstream from a cutting station (114) but upstream from a forming station (102), provides an outer surface that engages a clamp release surface (306) as the link member (300) passes over the sprocket.
