Abstract:
1. A rewinding machine for winding web material into logs around tubular cores, comprising: a tubular core insertion path; a winding cradle; a first moving member arranged to be in contact with web material to be wound; a rolling surface forming, with said first moving member, a channel for passage of tubular cores, said channel extending from an inlet, where a core is inserted into said channel, to an outlet from where the core moves into said winding cradle; an inserter for inserting said cores into the inlet of said channel; and a second moving member at said inlet of said channel and opposed to said first moving member, the core insertion path passing between said first moving member and said second moving member, and said first moving member and said second moving member being positioned at a distance such that a core inserted between said first moving member and said second moving member is in contact with the second moving member and with the web material entrained around the first moving member, the web material being nipped between the first moving member and the core; wherein speed of the first moving member and speed of the second moving member, at points of contact with the core, are oriented in opposed directions and controlled so as to cause rotation and forward movement of the core into said channel.
