Definitions

  • the present cutting device By means of the present cutting device according to the invention, the above drawbacks are avoided. At the same time a cutting device that is more dependable and reliable in operation is attained, which also produces a straighter and better-looking cut.
  • the device according to the invention When the device according to the invention is used in packaging activities, it has yet another advantage compared with previous embodiments in that when applying glue to the wrapping paper it applies glue all the way to the edge, thus avoiding a non-glued flap.
  • the adjustment of the knife in relation to the hammer is very painstaking and time-consuming, and the adjustment depends on the paper quality and the condition of the paper (degree of moisture), and readjustments must be made relatively frequently. This is avoided with the new cutting device, and a more continuous operation of the plant is achieved.
  • a cutting device being guided from one of the outer edges of the web to the other along a course running at an oblique angle to the outer edge of the web, with a speed which in relation to the feeding speed of the web is such as to allow a right angle or approximately right angle cut.
  • the cutting is performed using a cutting or slitting tool, which is guided along one side of the web, while running in a groove in a holding-on tool or base-table on the opposite side.
  • the cutting device comprises a cutting tool, for instance a knife, a nail etc., a device to give the cutting tool high speed, a holding-on tool or base-table with a slot in it, the slot adopting an oblique angle in relation to the outer edge of the running web, and the course of the cutting tool runs parallel with the plane of the running web.
  • the holding-on tool is rotatable to and from the cutting tool for catching the advancing web, and the holding-on tool is jointly constructed with a holding-on tool devised to press the web against a per se known roll for glue application.
  • a guide for the web is rotatably attached to the holding-on'tool for the glue application roll at the exit from the glue application roll.
  • the wrapping paper is guided through the gap 1, while the holding-on tool 7 is in a fully retracted position 2.
  • the paper is caught and guided by a guide 4 and brought forward and down towards the roll that is to be wrapped.
  • This roll is rotating at a minimum speed of at least that of the feeding speed of the paper, and the paper is applied to the roll in one or more layers - always with the holding-on tool in the rear position.
  • An adjustable length of web is to have glue applied to it, which occurs by the holding-on tool moving towards its second extreme position 3.
  • the paper web is lifted by the holding-on tool up towards a guide contour 5, next coming into contact with a glue application roll 6 for application of glue to one side of the paper web by means of a holding-on tool 8 which is assembled with the holding-on tool 7 of the cutting tool.
  • a fast-working fluid power cylinder 9 for cutting of the paper web a fast-working fluid power cylinder 9 is used, for instance an "Origa” cylinder, with a “rider” 10 connected to it which has a cutting tool 11 mounted on it, for instance a knife, nail, etc.
  • the cutting tool passes in a slot 12 in the holding-on tool, and the slot adopts an oblique angle in relation to the outer edge of the running web.
  • the glue application continues right to the edge of the web end that is wound on to the roll.
  • the other web end is retracted away from the cutting device and up towards the roll battery, so that the device may optionally receive paper of a different width.
  • the cutting device according to the invention may also be applied without the use of a holding-on tool or base-table to webs that are under tensile stress.
