The transfer device includes a web transfer assembly configured to receive a web from the web delivery assembly and configured to communicate with the core transfer assembly. The web transfer assembly includes a frame and lay-on roll moveably positioned relative to the frame. The web transfer assembly includes a vacuum hood moveably positioned relative to the frame. The vacuum hood has a cutting device mounted therein and one or more suction holding surfaces that are configured to releasably hold a portion of the web. The suction holding surfaces are movable relative to the frame and the core receiving structures. The suction holding surfaces communicate with the core receiving structures to transfer the web thereto. ## Claims ### Claim 1 A web transfer device for a multiple turret winder in a continuous web process line, the transfer device comprising: a web delivery assembly comprising at least one web delivery roll; a core transfer assembly comprising at least two core receiving structures; and a web transfer assembly configured to receive a web from the web delivery assembly and configured to communicate with the core transfer assembly, the web transfer assembly comprising a frame and lay-on roll moveably positioned relative to the frame, the web transfer assembly comprising a vacuum hood moveably positioned relative to the frame; the vacuum hood having a cutting device mounted therein, the vacuum hood having at least one suction holding surface, the at least one suction holding surface being configured to releasably hold a portion of the web, the at least one suction holding surface being movable relative to the frame and the at least one core receiving structure, the at least one suction holding surface communicating with the at least one core receiving structure to transfer the web thereto. ### Claim 2 (depends on 1) The web transfer device of claim 1, wherein the vacuum hood assembly comprises: a pivot assembly for pivotally mounting the vacuum hood assembly to a carriage; at least one chamber defined within the vacuum hood assembly; the at least one chamber having a first inlet defined by a first one of the at least one suction holding surfaces, the first at least one suction holding surface has a first plurality of holes extending therethrough; and the at least one chamber having a second inlet defined by a second one of the at least one suction holding surfaces, the second at least one suction holding surface has a second plurality of holes extending therethrough. ### Claim 3 (depends on 2) The web transfer device of claim 2, wherein the first inlet and the second inlet are spaced apart from one another defining a gap therebetween, and a plurality of rollers is positioned in the gap. ### Claim 4 (depends on 2) The web transfer device of claim 2, wherein the at least one suction holding surface is coated with a lubricious material. ### Claim 5 (depends on 4) The web transfer device of claim 4, wherein the lubricious material comprises PTFE. ### Claim 6 A method for transferring a web in a continuous web process line, the method comprising: providing a web transfer device for a multiple turret winder, the transfer device comprising a web delivery assembly comprising at least one web delivery roll, a core transfer assembly comprising at least two core receiving structures; and a web transfer assembly configured to receive a web from the web delivery assembly and configured to communicate with the core transfer assembly, the web transfer assembly comprising a frame and lay-on roll moveably positioned relative to the frame, the web transfer assembly comprising a vacuum hood moveably positioned relative to the frame, the vacuum hood having a cutting device mounted therein, the vacuum hood having at least one suction holding surface; stopping the web on one of the at least two core receiving structures; holding the web with the at least one suction holding surface; cutting the web with the cutting device to create a leading edge and a trailing edge; releasing the trailing edge from the at least one suction holding surface; securing the leading edge, via the at least one suction holding surface, to another of the least two core receiving structures. ### Claim 7 (depends on 6) The method for transferring a web of claim 6, wherein the cutting of the web is performed before indexing of the at least two core receiving structures with the core transfer assembly. ### Claim 8 (depends on 6) The method for transferring a web of claim 6, wherein the cutting of the web is performed after indexing of the at least two core receiving structures with the core transfer assembly. ### Claim 9 (depends on 6) The method for transferring a web of claim 6, wherein the trailing edge is released from the at least one holding surface before releasing the leading edge. ### Claim 10 (depends on 6) The method for transferring a web of claim 6, wherein the trailing edge is released from the at least one holding surface before indexing of the at least two core receiving structures with the core transfer assembly. ### Claim 11 (depends on 6) The method for transferring a web of claim 6, wherein the trailing edge is released from the at least one holding surface after indexing of the at least two core receiving structures with the core transfer assembly.
