Abstract
A process for manufacturing a product from strip tape starting from a broad web of material includes the step of separating the web into individual strips with a smooth stripping roll, conveying each strip in a vacuum conveyor channel, turning the strips on their way to the channel or in the channel by about 90°, leading the strips together at the end of the channel one upon the other and thereafter processing the strips to form the final product.
Claims9
A process for manufacturing a medicinal and/or an active substance containing product of at least two strip tapes, said process comprising the steps of:
- drawing a broad web of material in its entire width from a roll of material which is mounted loosely rotable on a take-up mandrel by a smooth stripping roll, which cooperates with a pressure roll and a guide roll in a zone in which the web of material travels around said smooth stripping roll;
- conveying said broad web of material by said smooth stripping roll to a multiple circular knife roll;
- separating said broad web of material into individual strips by rolling said multiple circular knife roll in cooperation with said smooth stripping roll;
- drawing each of said individual strips from said smooth stripping roll and introducing each of said individual strips into a vacuum conveyor channel;
- conveying each of said individual strips through said vacuum conveyor channel;
- turning each of said individual strips on its way to said vacuum conveyor channel or on its way through said vacuum conveyor channel by about 90°;
- allowing said strips at an end of said vacuum conveyor channel to lie one upon the other;
- and
- thereafter conveying said strips for further processing,
- wherein said individual strips are conveyed through said vacuum conveyor channel and led one upon the other by only a vacuum negative pressure.
A process for providing a plurality of individually stacked strips from a single web of material, the method comprising the steps of:
- providing the single web of material to a multiple circular knife roll with a smooth stripping roll;
- cutting the single web of material by the multiple circular knife roll into a plurality of strips having a predetermined width;
- rotating each of the plurality of strips from a first conveyance plane to a second conveyance plane, the second conveyance plane being substantially perpendicular to the first conveyance plane;
- drawing each of the plurality of strips into an individual vacuum conveyor channel;
- feeding each of the plurality of strips through the vacuum conveyor channel such that each of the plurality of strips are conveyed only by a vacuum generated within each vacuum conveyor channel;
- and
- placing each of the plurality of strips onto one another upon exiting the vacuum conveyor channel so that the plurality of strips are stacked.
