ABSTRACT OF THE DISCLOSURE A method and apparatus for presenting a serial succession of cut sheet portions to a work station. The sheet portions are cut from a continuous webbing which is processed by a cutting station and a web-breaking station. The cutting station partially severs the web downstream of its leading free end so as to define a first sheet portion between that free end and the point of cutting, with the first sheet portion connected to the web by one or more tab connectors. The webbing is then advanced downstream to the tab-breaking station where the tabs are broken to free the first sheet portion for independent movement further downstream. A vacuum belt engages the webbing, and particularly the downstream edge adjacent the partial severing, with a vacuum belt. The vacuum belt engages the webbing by bridging the partially-severed cut portion, so as not to interfere with the downstream tab-breaking apparatus. A continuous control over the cut sheet portions is provided prior to the breaking of the tab portion, and continues to the final delivery of the cut sheets.
