A web winding apparatus comprises two bobbins each being able to wind a web thereon; a cutter provided movably between the bobbin on one side and the bobbin on the other side for cutting the web being transferred; and a web pressing member provided at a position to face the cutter so that the web being transferred is put between the web pressing member and the cutter. The web pressing member is provided movably together with the cutter between the two bobbins, is configured to operate as cutter receiving member which presses and cuts the web in cooperation with the cutter, and is further configured to press a cut end of the web so cut on the bobbin being empty while holding the cut end of the web, to wind the cut end on the bobbin being empty.

Web winding apparatus

A web winding apparatus comprises a cutter, a web pressing member and a roller which are movable together between two bobbins supported respectively by two rotational center members. The cutter cuts a web being transferred, the web pressing member presses an end portion of the web cut with the cutter on the bobbin being empty, and the roller transfers the web being transferred to come, toward the bobbins. The apparatus further comprises two peripheral covers independently turnable around the rotational center members and respectively covering parts of outer peripheral surfaces of the webs wound on the two bobbins. Each of the peripheral covers respectively having circumferential openings is turnable selectively to a first position to direct the circumferential opening toward the roller and a second position to partition the bobbin side covered thereby and the roller side.

A laser beam machine for processing an article to be processed with a laser beam from a processing scannercomprised of an optical system employing a laser oscillator. Article position controllersandare controlled in a coordinated manner in accordance with the direction of the laser beam from said processing scannersuch that the position of a surface to be processed of the article is controlled to be nearly perpendicular to the direction of the laser beam from the processing scanner. While an article to be processed mounted on one article position controlleris being processed and unloaded, another article to be processed can be loaded onto the other article position controllerThus, the wait time for the laser beam machine can be reduced and production efficiency can be improved.
