A method for separating a first mechanical part from a second mechanical part is described, wherein the second mechanical part is bonded to the first mechanical part by an adhesive film along a connecting area, the first mechanical part having a first specific thermal conductivity and the second mechanical part having a second thermal conductivity that is higher than the first thermal conductivity. The method includes at least one cooling step during which the second mechanical part is cooled to a negative temperature and at least one stressing step during which the second mechanical part is subjected to mechanical stress in order to cause the adhesive film to break.

A method for removing a support structure in a component produced by additive manufacturing provides that explosive gas introduced into a pressure chamber is ignited, wherein a gas conveying device with which the flame front is guided into the cavity is also additionally provided in the chamber. A tool for carrying out the method is also indicated.

A method and an apparatus are provided for opening value document packages in which value documents are packaged by a packaging material. A region of the packaging material is heated by hot air such that the packaging material opens along a cutting pattern. A system is also provided that includes such an apparatus and a value document package.

A method for manufacturing a sanitary cover for a beverage can and relates to a technique for forming a cutting line along a circumferential surface of a sanitary cover while the sanitary cover is covering a beverage can, thereby maximizing the production efficiency of the sanitary cover having improved functionality. Also, the technique which, in three-dimensionally forming a cutting line as such, can carry out the process of forming the cutting line easily and rapidly via a simple structure, thereby increasing the production efficiency even further.

A method for laser preparation of a coated substrate to be laser cut is provided. The method includes substantially removing a target portion of a polymer coating from a coated substrate by directing an ablative laser beam to the target portion, wherein the target portion of the polymer coating has a width of between about 10 m and about 6.0 mm.

An apparatus includes a structure comprising a predetermined breakable region and a mechanical actuator disposed at or proximate the predetermined breakable region. The mechanical actuator comprises an impact member coupled to a spring arrangement, and a restraint member operably coupled to the spring arrangement. A trigger source is operably coupled to an electrical power source. The trigger source, in response to receiving current from the electrical power source, is configured to release or break the restraint member so as to allow the spring arrangement to forcibly move the impact member into contact with, and break, the predetermined breakable region.
