Abstract
A method and device for cutting hollow glass articles (1) by laser, comprising a first stage in which an incision is made along the circumferential cutting line in the articles, which are rotating about their axis. The article is rotated about its axis. The incision is made by a focused laser beam (3). The article, simultaneously with the incision, is blasted in correpondence with the irradiated point by a pressurized jet of a fluid for cooling and cleaning the incision channel.
Claims15
A method for cutting a hollow glass article using a laser, comprising the steps of:
- rotating the article about an axis;
- forming an incision channel by vaporizing said article along a circumferential cutting line of the glass article by a laser irradiating the circumferential cutting line;
- and
- simultaneously with forming the incision channel, cooling and cleaning the incision channel using a pressurized jet of fluid.
A method for cutting a hollow glass article using a laser, comprising the steps of:
- rotating the article about an axis;
- forming an incision channel around the circumference of the glass article by a laser beam of the laser;
- simultaneously with forming the incision channel, cooling and cleaning the incision channel using a pressurized jet of fluid;
- heating the glass article;
- and
- striking the glass article to cut the glass article along the incision channel if this has not already occurred.
A device for cutting hollow glass articles, comprising:
- means for rotating the articles about their axis;
- glass evaporation means for making an incision channel in the article corresponding to a circumferential cutting line, wherein the glass evaporation means is a laser and makes the incision channel along the entire circumferential cutting line by using said laser to irradiate vaporize the circumferential cutting line as the article is rotated about its axis;
- and
- a member for simultaneously cooling and cleaning the incision channel as the circumferential channel is being irradiated.
A device for cutting a hollow glass article, comprising:
- means for rotating the article about an axis;
- a laser for making a circumferential incision channel in the article;
- means for cooling and cleaning the incision channel;
- means for heating at least the part of the article which corresponds with the incision channel;
- and
- percussion means for striking the article such that it is cut along the incision channel.
