Abstract: 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.

Abstract: A support mechanism for an electronic paper comprises a base, a fixing module and a supporting element. The electronic paper is installed on the fixing module. The supporting element is connected to the base and the fixing module.
Abstract: A core infeed apparatus for a surface winder moves an elongated core axially into the winder while an axial line of glue is applied to the core. The core is moved into a space between a pair of rotatable core guides. One of the core guides is rotatable away from the core while the other core guide rotates the core toward a core inserter. The core is transferred to the core inserter, and the core inserter rotates to move the core toward the winding rolls of the rewinder. The position of the glue line is accurately maintained as the core moves to its various positions.
