Abstract
A method and an apparatus for forming packages including plasters enclosed between two opposite flexible sheets having their edges joined by means of a thermally-activated adhesive.
Claims10
A method for packaging plasters, comprising:
- in a first step at a first station, enclosing said plasters between two opposite flexible sheets, at least one of which has thermally-activated adhesive on its surface facing the other sheet,
- in a second step, distinct and separate from said first step, compressing said sheets to peelably fix said sheets together around said plasters by means of said thermally-activated adhesive, wherein the second step is performed at a second station, which is downstream from and separate and distinct from the first station, and
- carrying out a preliminary heating of at least one of said sheets at the first station before compressing said sheets, and a final heating of said at least one of said sheets simultaneously to compressing said sheets at the second station.
An apparatus for packaging plasters, comprising:
- an overlapping unit configured to apply two flexible sheets on opposite sides of said plasters, so as to enclose said plasters between said sheets,
- a compression unit distinct and separate from and downstream of said overlapping unit, and configured to compress said sheets at compression areas to form a peelable seal, and
- a preliminary heating unit configured for heating at least one of said sheets before compressing said sheets and a final heating unit configured for heating at least one of said sheets at said compression unit, wherein the preliminary heating unit is separate and distinct from and upstream of the compression unit.
