摘要:
In order to avoid in a tubular bagging machine the disadvantages resulting from the state of the art through a cam-plate control of cross-welding jaws, it is suggested according to the invention, that the control of the movement of the cross-welding jaws occurs in dependency on the contact pressure, the temperature and the needed sealing time, with the drive being able to occur mechanically by means of a toggle-lever drive mechanism.

A document processing system may include a document scanner for collecting document image data for a given copy project for a given user, a document printer, and a controller. The controller may cooperate with the document scanner to retain document image data for the given copy project if a printing cost therefor is greater than a copy account value for the given user. The controller may thereafter cooperate with the document printer to print the retained document image data for the given copy project based upon an increase in the copy account value to at least equal the printing cost.
