Claim 6:
7. A method for manufacturing biodegradable whole leaf pillow tea bags, the method comprising the steps of:
providing a continuous sheet of biodegradable infusion material having opposing free side ends;
feeding the sheet of biodegradable infusion material downward into a sealing and cutting system having a tea dispensing mechanism attached thereto, where the tea dispensing mechanism includes an inlet for receiving whole leaf tea, an auger for dispensing predetermined amounts of whole tea leaf into a feeding tube in amounts to create single whole leaf pillow tea bags;
forming the biodegradable infusion material into a tubular member by wrapping the biodegradable infusion material around a vertical tube on the sealing and cutting system;
joining and sealing the opposing free side ends of the biodegradable infusion material wrapped around the tube with a vertical sealing mechanism to create a sleeve;
advancing the vertically sealed tubular biodegradable infusion material past the lower end of the tube on the sealing and cutting system until it reaches a horizontal sealing mechanism;
creating a horizontal seal along a bottom of the tubular biodegradable infusion material with the horizontal sealing mechanism, where the horizontal sealing mechanism includes a central channel housing a cutting mechanism that is supported by an actuating mechanism that actuates the cutting mechanism from within the central channel of the horizontal sealing mechanism to cut through the center of the horizontal seal;
depositing a predetermined amount of whole leaf tea in the bottom of the tubular biodegradable infusion material by dispensing a predetermined amount of whole leaf tea through the tube on the sealing and cutting system;
advancing the tubular biodegradable infusion material below the horizontal sealing mechanism such that the whole leaf tea deposited in the bottom of the tubular biodegradable infusion material is below the horizontal sealing mechanism; and
sealing the tubular biodegradable infusion material to create a top seal on the tubular biodegradable infusion material below the horizontal sealing mechanism and cutting the seal at its middle with the cutting mechanism to create a biodegradable pillow tea bag.
