A tensioning control device having a first motor that applies a torque to a first end of a substrate in a first direction and a second motor that applies a torque to a second end of the substrate in a second direction that is generally opposite the first direction is disclosed. In this manner, the first motor and the second motor apply torque to the substrate in opposing directions, thereby placing the substrate in tension. In one embodiment, the first motor applies a torque to the first end of the substrate that is equal to the torque applied to the second end of the substrate by the second motor. By placing the substrate in tension in this manner, an actuator is able to incrementally move the substrate in a forward direction and a backward direction independent of the tension applied to the substrate.

A packaging machine which unwinds a bottom film web from a supply roll and conveys it intermittently or continuously along the packaging machine and in a forming station, forms into the bottom film web packaging cavities, which are then filled with a product to be packaged. In a sealing station, a top film web is sealed to the bottom film web, wherein the bottom and top film web are respectively unwound from a supply roll and the bottom and top film web are respectively tensioned by means of a dancer roll. The supply roll is driven by means of a motor, the parameters of which, in particular rotation speed and/or torque, can be set on the basis of the parameters of the respective supply roll.

An adjustable tightening device is provided, including: a fastening, an actuating member and a rotatable member. Wherein when the rotatable member is rotated toward a first direction, each abutting rib of the rotatable member is located in the third position, each of the two abutting ribs abuts against one of two elastic arms of the actuating member so that a ratchet is not meshed with an annular gearing portion of the fastening mechanism and a gear portion of the actuating member is rotatable toward the first direction; wherein when the rotatable member is rotated toward a second direction, each of the two abutting ribs is located in the fourth position, each of the two abutting ribs abuts against one of the two elastic arms so that the ratchet is meshed with the annular gearing portion and the gear portion is unidirectionally rotatable toward the second direction.

A corrugated sheet processing apparatus (120) is disclosed, comprising feed and guide rollers for selecting, moving and supporting sheets or webs to a corrugator (136) for forming a corrugated sheet; and a control system for controlling the sheet processing equipment (136) or a cutter (148); the sheet processing apparatus (136) further comprising a visual inspection unit (162) for reading printed information markers on at least one printed sheet or web as the printed sheet or web pass through the corrugated sheet processing apparatus (136) or corrugator; and wherein the control system further has a data look-up table whereby the apparatus (120) can identify what products will be produced downstream of the visual inspection unit, and the required settings for the sheet processing equipment or corrugator for those products.
