<p>An automatic paper web connecting apparatus includes a pair of blocks (70,70') arranged so as to be able to move relatively and be pressed against each other in the direction to cross a feed path for one paper web and a feed path for the other paper web, retaining mechanism for retaining the two paper webs on the respective opposite faces of their corresponding blocks by suction, a cutting mechanism for cutting a desired one of the paper webs, and a drive mechanism for relatively moving the blocks. The cutting mechanism includes a rotating body (66) rockable between the two paper web feed paths on the upper-course side of the blocks, first and second knives (86,86') fixed individually to the blocks, and a third knife (81) fixed to the rotating body. The rotating body is rotated between a first rotational position in which the third knife faces the first knife and a second rotational position in which the third knife faces the second knife. The desired one paper web is cut by means of the third knife and one of the first and second knives, which is selected depending on the rotational position of the rotating body, while the blocks are moving relatively to each other. <IMAGE></p> |
