A device is provided for carrying out the process. A device for gripping a part of a material web as well as to a system for gripping a part of a material web is provided as well as a process for gripping a material web. A device is provided for applying a double-sided adhesive tape to a surface as well as to a system with such a device, and a process for applying a double-sided adhesive tape to a surface.
Claims44
A process for preparing a winding roll for a flying roll change by arranging an adhesive tape between the beginning of the web and a web layer of the winding roll, which said web layer lies under it, the process comprising:
- lifting the beginning of the web off from the winding roll;
- placing the adhesive tape with a first bonding surface on the area of the said web that has remained wound up;
- cutting the beginning of the web to size;
- and
- returing the beginning of the web, which has been lifted off and cut to size, onto the sad winding roll, so that a second bonding surface of the adhesive tape comes into contact with the beginning of the web.
A process for preparing a winding roll for a flying roll change by arranging a adhesive tape between the said beginning of a web and a layer of the winding roll lying under it, in which:
- lifting the beginning of the web off from the winding roll;
- placing the adhesive tape on the web;
- cutting the beginning of the web to size;
- leading the beginning of the web is led over a roller for cutting the beginning of the web to size;
- and
- pressing a sad cutting knife against the roller, so that a cutting blade of the cutting knife is pressed against the circumferential surface of the roller and the web is severed.
A device for lifting the beginning of a web off from a winding roll, placing adhesive tape on the web and cutting the beginning of the web to size the device comprising:
- a gripping device for lifting off the beginning of a web of the winding roll;
- a an adhesive tape applicator for placing an adhesive tape on the web of the winding roll, the adhesive tape applicator being arranged such that the adhesive tape can be placed on an area of the web on the jacket surface of the winding roll, which said web area has remained wound up, and from which the beginning of the web was lifted off.
A device for gripping a part of a material web, the device comprising:
- a first element;
- and
- a second element, which can be moved in relation to the first element, wherein a part of the first element can be placed on the material web and the second element can mesh with the material web, so that the material web can be gripped between the first element and the second element by a relative movement between the first element and the second element.
A system for gripping a part of a material web, the system comprising
- a material web holding device;
- a device for gripping the material web with a first element and a second element, which can be moved in relation to the first element, wherein a part of the first element can be placed on the material web and the second element can mesh with the material web, so that the material web can be gripped between the first element and the second element by a relative movement between the first element and the second element;
- and
- a moving element to move the device for gripping the material web in relation to the material web holding device.
A process for gripping a material web, the process comprising the steps of:
- placing a first element on the material web;
- bringing a second element into meshing with the material web;
- and
- holding the material web between the first element and the second element by a relative movement between the first element and the second element.
A device for placing a double-sided adhesive tape on a surface, the device comprising:
- an adhesive tape feeding device for feeding the double-sided adhesive tape masked with at least one masking tape,
- a separating device for separating the double-sided adhesive tape from the at least one said masking tape,
- a cutting device for cutting the double-sided adhesive tape;
- and
- an adhesive tape pressing device for bringing together and/or pressing on the double-sided adhesive tape, wherein the at least one masking tape is led between the adhesive tape pressing device and the double-sided adhesive tape which is to be pressed on.
A process for placing a double-sided adhesive tape on a sad surface, the process comprising:
- pulling a masking tape covering the double-sided adhesive tape is off from the double-sided adhesive tape;
- severing the adhesive tape after a predetermined length;
- and
- pressing the double-sided adhesive tape onto the surface by a pressure applied on the masking tape which has been returned.
