Device for packaging items, in particular confectionery, such as for example lollipops, comprising a packaging conveyor having a series of holders rotating along a movement path for holding each item and its associated packaging sheet securely during conveying, a feed station for feeding the items and the packaging sheets to the packaging conveyor and a discharge station for discharging the items packaged on the conveyor, the packaging conveyor being provided with means for closing the packaging sheet on the respective item and with a series of heat-sealing means co-rotating with the holders for heat-sealing the closed packaging by supplying heat, each of the heat-sealing means comprising a sheet gripper which is provided with a heating body, the device furthermore comprising means for heating each heating body and means for controlling the heating means, the control means being designed for controlling the heating means for each heating body.
A method of packaging items, comprising the steps of providing a conveying rotating driven drum having a series of holders for holding at least one item and at least one packaging sheet securely during conveying, feeding the at least one item and at least one packaging sheet to the packaging conveyor and discharging the at least one item packaged on the conveyor, closing the at least one packaging sheet on the respective item and heat-sealing and co-rotating with the holders for heat-sealing, the heat-sealing means comprising a sheet gripper which is provided with a heating body, heating each heating body and controlling the heating means, the control means comprising one control system, a memory for discrete storage of the measured values of the heating bodies and being provided with a memory for storing a desired value of the temperature of the heating bodies, measuring the temperature of each heating body, controlling the heating means by way of the control means for that heating body based on the result of a comparison between the desired value and the last measured value of a heating body.
