Packaging apparatus comprising two counter-rotatable sealing dies for pressing together two tissue webs to produce pockets for containing a substance for preparing beverages and to seal around said pockets, and two heating drums for heating the sealing dies and each being positioned inside a respective sealing die, wherein a first heating zone of each heating drum comprises a first plurality of circumferentially distributed infrared heating elements, and a second heating zone of each heating drum comprises a second plurality of circumferentially distributed infrared heating elements.
Packaging apparatus comprising two counter-rotatable sealing dies for pressing together two tissue webs to produce pockets for containing a substance for preparing beverages and to seal around said pockets, and two heating drums for heating the sealing dies and each being positioned inside a respective sealing die, wherein each heating drum comprises a plurality of circumferentially arranged infrared emitters, wherein the infrared emitters each comprise a short wave carbon infrared element in a quartz glass tube.
A method for packaging a substance for preparing beverages, the method comprising:
- counter-rotating two sealing dies;
- heating, by a respective heating drum, each one of said two counter-rotating sealing dies;
- pressing, by the two counter-rotating sealing dies, two tissue webs together to produce pockets for containing the substance;
- and
- sealing, by the two counter-rotating sealing dies, around the outside of said pockets;
- wherein a first heating zone of each heating drum comprises a first plurality of circumferentially distributed infrared heating elements, and a second heating zone of each heating drum comprises a second plurality of circumferentially distributed infrared heating elements.
