The present invention provides a perforating station comprising two or more discrete perforating stations, the stations synchronized with one another to cut a line of perforations across a web, such as a web of tissue paper, moving at high speeds. By providing two or more synchronized perforating stations the perforating station may increase the number of impacts per minute compared to prior art perforating devices.

Registration and inspection systems and methods for use on a winder are disclosed. The systems and methods include scanning a region proximate a winding module with one or more sensors to determine a product defect. The product defect is then associated with a winding process parameter, such as percent roll build information or the identity of the particular sensor to first detect the defect. The winding process parameter is used to classify the defect into one or more defect profiles. The defect profiles can be based at least in part on segmenting the roll build of a web onto a winding module into a plurality of inspection windows and segmenting a plurality of sensors into a plurality of inspection sensor segments.

Winder registration and inspection system

Coreless rolls of tissue, such as rolls of bath tissue or paper towels, are produced by winding tissue logs on a mandrel having retractable pins. During winding, the pins extend and penetrate the first several windings of the log as it is initially wound, which prevents slippage. After the winding is complete, the pins retract to allow the tissue log to slide off of the mandrel for subsequent slitting into individual product rolls and packaging. The penetration of the pins into the first several windings of the log tends to mechanically entangle and structurally unify those windings to create a 'soft core'. At the same time, the properties of the tissue sheets within the soft core are the same as the other sheets within the roll and are therefore usable by the consumer.

Coreless tissue rolls

A web winding and measuring system is provided. The system includes a rotatably-mounted spool onto which a web of material is wound to form a roll. The system additionally includes a light-emitting device configured to illuminate the roll by light, providing a line on a cylindrical surface of the roll in a cross-machine direction, a light-receiving device configured to detect the line and generate measurement data from the detected line, and a computing device communicatively coupled to the light-receiving device and configured to receive the measurement data and calculate a diameter of the roll.
