Abstract: A method is described for obtaining a coreless roll of web material with a first portion of web material forming an inner nucleus of the roll and a second portion of web material wound around the outside of the inner nucleus. The two portions can be separated from one another and, for that purpose, an interface or discontinuity is created in at least one turn of the web material forming the roll between the inner nucleus and the second portion of web material. This facilitates the extraction of the inner nucleus from the outer portion of the roll.

Abstract: A method and apparatus is provided for semi-automatically applying a label to a cylindrical container. The method comprises the steps of removing a label from a label repository and transporting it into contact with a glue-retaining surface and then into contact with a rotating cylindrical container. The cylindrical container is rotated at a surface speed which is slightly faster than the speed at which the label is moved past the glue-retaining surface. Therefore, when the leading edge of the label comes into contact with the rotating cylindrical container, the central portion of the label is pulled away from the glue-retaining surface. As the label is drawn by the rotating cylindrical container, the trailing edge of the label is caused to contact the glue-retaining surface. By this method, glue is automatically applied to the leading edge and to the trailing edge of a label but not applied to the central portion of the label, and the label is automatically applied to a cylindrical container.

Abstract: An improved apparatus and method are disclosed for winding into a spiral roll the positive (186) and negative (241) plates of small cylindrical batteries. The originally flat positive and negative pasted plates are conveyed through stations at which they are automatically wrapped with strips of separator material (24, 84).
