DEVICE AND METHOD FOR MANUFACTURING A BAG RECEIVED IN AN ENVELOPE

The present invention relates to a device and a method for manufacturing a bag received in an envelope and containing a brewable material with a bag manufacturing means which is configured to manufacture a bag containing brewable material, and with a sealing station with a sealing jaw element and a counter-jaw element which act on the envelope from opposite sides to seal in the bag. The device is further developed for a reliable and safe manufacture of the packing unit consisting of a bag and an envelope by the sealing jaw element being fixed to a sealing jaw swivel arm at which a sealing jaw connecting rod is applied, and the counter-jaw element being fixed to a counter-jaw swivel arm at which a counter-jaw connecting rod is applied, and by the sealing jaw connecting rod and the counter-jaw connecting rod being each eccentrically connected to a common drive shaft of a servomotor. In the method according to the invention, the contact force between the sealing jaw element and the counter-jaw element is controlled via the torque of the servomotor actuating the sealing jaw element and/or the counter-jaw element.

DEVICE FOR MANUFACTURING A POUCH ACCOMMODATED IN A WRAPPING

Vacuum packaging and sealing appliance

The invention comprising an appliance for vacuum sealing a bag member. The appliance has a housing including a front wall, a rear wall, and two side walls. The front wall includes an opening for receiving an open top portion of the bag member, where the bag member can then be received within a drip tray placed within a cavity located within the housing, where vacuum pressure may be applied. The drip try includes a barrier member that extends upwardly at a rear portion to redirect the open top portion of the bag member into the drip tray when the bag member has been inserted into the opening. The cavity also includes a heating bar used to apply a seal to the open top portion of the bag member. The front wall of the housing is angled between 15° and 45° relative to a surface on which the appliance rests.

A method and apparatus for sealing a plastic enclosure is provided. The apparatus includes a handle including elements pivotally coupled together at a first end. The apparatus also includes a heating element positioned along an inner surface of an element and connected to a power source where a longitudinal axis of the heating element is oriented parallel with a longitudinal axis of the element. Plastic material including first and second plastic layers is positioned at an interface between the second elements. Upon pivoting the first elements from an open position to a closed position the heating element increases a temperature at the interface to melt the plastic material and form a seal between the first and second plastic layers.

Bag sealing apparatus and bag sealing method

A vibration measurement device measures vibration of at least one of the first sealing member and the second sealing member. A determination device determines quality of the sealing process according to a measurement result of the vibration measurement device from before the first sealing member and the second sealing member reach the closed position to after the first sealing member and the second sealing member reach the closed position. The sealing drive unit causes relative movement between the first sealing member and the second sealing member from an open position at a moving speed determined according to a type of the bag, to place the first sealing member and the second sealing member in the closed position.
