ABSTRACT:
When the winding operation is started, the leading edge portion of the sheet is sucked and held by one of a pair of horizontally disposed rollers and the extension of the leading edge portion of the sheet beyond the one roller is controlled by rotation of said one roller. An adhesive with a suitable viscosity is sprayed against a core from the position below the core. The core and said one roller are rotated so that the sheet is clamped between the one roller and the portion of the core which is applied with the adhesive and consequently is bonded to the core. Thereafter the pair of rollers are rotated at a low speed so that the slack of the sheet is eliminated. Next the sheet is wound around the core at a high speed. After the winding operation, an adhesive with a suitable viscosity is sprayed against a roll of paper from below so that the sheet is bonded by the weight of the roll of paper itself. Thereafter the sheet is cut off and the roll of paper is pushed out.
