FIELD: instrument engineering.
SUBSTANCE: invention relates to a device for wrapping a sheet of a wrapping material around a core product, herewith the device comprises a rotary drum having a central longitudinal axis, wherein the circumferential surface of the drum comprises a row of grooves extending in the direction parallel to the central longitudinal axis of the drum, each groove is designed to hold the core product inside it, which comprises at least one brittle segment, the circumferential surface of the drum further comprises attachment portions arranged between the grooves, herewith each attachment portion is designed to hold the sheet of the wrapping material, wherein the sheet of the wrapping material has an adhesive coating, and the device further comprises a rolling mechanism having a contact surface located at a predetermined distance from the circumferential surface of the drum, herewith the predetermined distance is selected so, that the contact surface must be in contact with the periphery of the corresponding article to be wrapped in the corresponding groove in such a way, that it causes the core product to exit from the groove and to roll on the outer surface, onto which there is the adhesive coating, of the sheet of the wrapping material held onto the adjacent attachment portion, as the result of which wrapping the sheet of the wrapping material around the core product is provided, wherein at least a portion of the contact surface is resiliently displaceable away from the circumferential surface of the drum.
EFFECT: technical result is to provide the possibility of wrapping brittle core products.
