ABSTRACT:
A tissue paper winding and cutting machine includes a first winding roller, at least one core support plate arranged near the first winding roller to form a channel between them, and a pre-winding roller arranged near and below the first winding roller with a circumferential surface facing toward the first winding roller and protruding into the channel to form a narrowed passage in the channel. The pre-winding roller rotates about a shaft thereof in a direction opposite to a predetermined moving direction of a tissue paper to be wound around cores, and at a rotation speed slower than that of the first winding roller. With the rotation speed difference between the pre-winding roller and the first winding roller, a core moved into the channel is temporarily held at the narrowed passage, so that the tissue paper fed into the channel is wound around the core before being pulled broken.
