DISPENSER Russian patent published in 2018 - IPC B65H37/00 

FIELD: technological processes.

SUBSTANCE: invention relates to the field of unwinding mechanisms. Unwinder is designed to dispense sticky material. Sticky material has at least one adhesive side that covered by the substrate. Substrate has a longitudinally extending slit. Material of the substrate is rolled up into a roll in the form of an Archimedean spiral. Slot is under the material covered by the substrate. Unwinder consists of a frame, a first guide and a second guide. At one end of the frame there is a holder for a roll of material. Holder is made with the possibility to rotate the roll. First guide device directs the material together with the substrate to the first dispensing edge. At least one first substrate strip is removed on the first edge. Substrate is divided by the slots under the material. Second guide device directs the material with the remaining second stripe of the substrate to the second dispensing edge. At the second edge, the remaining second strip of the substrate is removed.

EFFECT: it is possible to remove easily the material with an adhesive layer from the substrate.
