With this arrangement, the sticks are destacked quickly and reliably, making it possible to achieve high operating rates, either when the sticks are placed directly in front of an ice-cream body, or when the sticks are inserted in pockets on a carrier belt (8). In the latter case, said belt (8) may have pockets or fingers with a substantially greater depth or height, respectively, than the thickness of an ice-lolly stick, so that the stick is held more securely during the further conveying. ## Claims ### Claim 1 A device for separating and conveying sticks in an apparatus for inserting sticks in ice-lolly bodies in which the sticks are supplied in the form of an elongate stack of sticks in a guide having an exit aperture, said device comprising: at least one destacking rotor for destacking the sticks at the exit aperture and for transferring the sticks therefrom singly, said rotor comprising at least one recess shaped and dimensioned to destack one stick from the stack of sticks at the exit aperture; and a carrier moving past the exit aperture of the guide to which the sticks destacked by said destacking rotor are transferred by said destacking rotor, the sticks being carried by said carrier to ice-cream moulds and placed in a delivery position aligned to the ice-lolly bodies, said carrier including a belt having a means for receiving the sticks transferred by said destacking rotor. ### Claim 2 (depends on 1) A device according to claim 1, wherein an edge plane in each recess in the destacking rotor constitutes a first support plane and at least approximately constitutes a meridian plane in the rotor and has a radial extent adapted to the thickness of the sticks to be destacked while acted upon by said edge plane. ### Claim 3 (depends on 2) A device according to claim 2, wherein a plane surface in each recess in the destacking rotor constitutes a second support plane extending mainly as a truncated chordal plane from the periphery of the rotor to the edge plane constituting said first support plane. ### Claim 4 (depends on 1) A device according to claim 1, wherein the destacking rotor comprises two generally disc-shaped parts axially mutually spaced to provide an interspace therebetween, so that the sticks are supported by said disc-shaped parts. ### Claim 5 (depends on 1) A device according to claim 1, wherein the destacking rotor is made of wear-resisting material. ### Claim 6 (depends on 1) A device according to claim 1, wherein the destacking rotor is adapted to be driven intermittently. ### Claim 7 (depends on 1) A device according to claim 1, wherein the destacking rotor is adapted to be driven continuously. ### Claim 8 (depends on 1) A device according to claim 1, wherein the belt of the carrier has a run including an arcuate portion, wherein the destacking rotor is adapted to deliver the sticks to the carrier at a position immediately upstream of the arcuate portion, and wherein the receiving means on the carrier for receiving the sticks are situated on the outside of the arcuate portion wherein the receiving means are made to open to facilitate the receiving of the sticks. ### Claim 9 (depends on 1) A device according to claim 1, wherein the carrier is in the form of an endless belt. ### Claim 10 (depends on 1) A device according to claim 1, wherein the dimension of the receiving means on the carrier as measured at right angles to the latter is greater than the thickness of the sticks. ### Claim 11 (depends on 1) A device according to claim 1, wherein the carrier comprises two supporting surfaces adapted to support the sticks in two regions adjacent to the receiving means and having a distance between said two supporting surfaces in the longitudinal direction of the sticks received in the receiving means. ### Claim 12 A device for separating and conveying ice-lolly sticks having a flat rectangular cross-section comprising: a guide means for supplying the ice-lolly sticks as an elongated stack of ice-lolly sticks, the guide means having an exit aperture, at least one destacking rotor at the exit aperture of the guide means, for destacking the ice-lolly sticks at the exit aperture, said destacking rotor including at least one recess shaped and dimensioned to destack one ice-lolly stick from said stack of ice-lolly sticks, said recess having (a) an edge plane that constitutes a first support plane which at least approximately constitutes a meridian plane in the destacking rotor and that has a radial extent adapted to the thickness of the ice-lolly sticks to be destacked while acted upon by said edge plane, and (b) a plane surface that constitutes a second support plane extending mainly as a truncated chordal plane surface from the periphery of the destacking rotor to the edge plane constituting the first support plane, the transition from the periphery of the destacking rotor to the chordal plane surface being smooth, and a carrier including a belt having a means for receiving the sticks, said destacking rotor being adapted to deliver the sticks to the belt, after which the carrier conveys the sticks to a delivery position for insertion in ice-lolly bodies. ### Claim 13 (depends on 12) A device according to claim 12, wherein the destacking rotor comprises two generally disc-shaped parts axially mutually spaced to provide an interspace therebetween, so that the sticks are supported by said disc-shaped parts. ### Claim 14 (depends on 12) A device according to claim 12, wherein the destacking rotor is made of wear-resisting material. ### Claim 15 (depends on 12) A device according to claim 12, wherein the destacking rotor is adapted to be driven intermittently. ### Claim 16 (depends on 12) A device according to claim 12, wherein the destacking rotor is adapted to be driven continuously. ### Claim 17 (depends on 12) A device according to claim 12, wherein the belt of the carrier has a run including an arcuate portion, wherein the destacking rotor is adapted to deliver the sticks to the carrier at a position immediately upstream of the arcuate portion, and wherein the receiving means on the carrier for receiving the sticks are situated on the outside of the arcuate portion whereby the receiving means are made to open to facilitate the receiving of the sticks. ### Claim 18 (depends on 12) A device according to claim 12, wherein the belt of the carrier is an endless belt. ### Claim 19 (depends on 12) A device according to claim 12, wherein the depth dimension of the receiving means on the carrier is greater than the thickness of the sticks. ### Claim 20 (depends on 12) A device according to claim 12, wherein the carrier comprises two supporting surfaces adapted to support the sticks in two regions adjacent to the receiving means and having a distance between said two supporting surfaces in the longitudinal direction of the sticks received in the receiving means.
