Definitions

  • the wire cutting method offers great advantages over the other known method sometimes used in dividing up cellular light weight concrete bodies and which comprises sawing the molded bodies first when the latter have been already hardened, but nevertheless the wire cutting method is not completely satisfactory in the way it has hitherto been applied.
  • the wire cutting method in its earlier fashion renders cut surfaces of a rather coarse structure, which fact makes the wire cut light weight concrete products less adaptable to certain applications within the modern building industry and, above all, makes the light weight concrete pieces separated by the cuts more liable to again bind together or cake during the steam hardening process, which ordinarily follows the cutting operation, so that the pieces must be forced apart in a rather rough manner easily resulting in a considerable rejection percentage.
  • the cut up products will present a very dust-laden surface after having been steam hardened so that they are rather disagreeable to handle.
  • the present invention has for its object to meet this demand and relates to a modified wire cutting method which is chiefly characterized in that at least two wire sections or card sections are caused to pass through the body the one behind the other in relatively close order to oo- "ice operate in producing one and the same cut.
  • the foremost wire section as calculated in the cutting direction, then effects the actual cutting while the subsequent wire section or wire sections will have a smoothing and probably also compressing effect on the cut surfaces left behind by the first Wire section.
  • each thinner Wire section being followed by a thicker one.
  • the thicker wire section or cord section should then suitably have a thickness which is not more than twice the thickness of the preceding wire section or cord section.
  • wire sections or cord sections which are caused to move longitudinally during their passage through the semiplastic "body in the cutting direction.
  • the wire sections or cord sections may, if desired, be provided with sawtooth-like projections, but this is not in any way necessary since also completely smooth wires or cords will render a more favorable cutting result when the combined movement referred to is used.
  • the movement of the wire sections or cord sections in their longitudinal direction may be either continuous or reciprocative. In both cases the speed of longitudinal movement should be moderate in relation to the speed at which the Wire section or cord section is passing through the body in the cutting direction. It has been found most desirable to co-ordinate the movements of the Wire sections following each other in the same cut in such a manner that, if the foremost wire section, as calculated in the cutting direction, passes a certain surface portion in the cut while moving longitudinally in the one direction, the very next Wire section will move longitudinally in the opposite direction while passing the same surface portion. In practice, however, such an ideal co-ordination is sometimes difficult to achieve, particularly if reciprocat-ory movements are imparted to the wire section, and practical tests have proved that acceptable results can be obtained also without it.
  • FIG. 4 is a diagrammatic sectional elevational of a second form of cutting apparatus taken along a plane in which two wires section are passing through a semi-plastic light weight concrete body to produce in cooperation a cut therein,
  • FIG. 5 is a diagrammatic sectional elevation similar to that of FIG. 4 but showing a modified form of cutting apparatus and FIG. 6 is a diagrammatic sectional elevation of a fourth form of cutting apparatus using two entirely separate wires to produce a cut in a semi-plastic body.
  • a semi-plastic body B for instance of cellular, 'unhardened light weight concrete, is being divided up or cut by being moved relative to two vertically stretched wire sections 1 and 2 respectively which are substantially parallel and located the one behind the other in line with the direction of cutting.
  • the cutting may equivalently be accomplished in such a manner that the wire sections 1 and 2, which are supposed to be stretched in a frame, a yoke or a similiar holding device, are moved relative to the body B in the intended direction of cutting.
  • the thickness of the wire section 2 can either be the same as that of the wire section 1 or, more preferably, somewhat larger. The difference in thickness should, however, not be exaggerated since this may hazard the result.
  • the following wire section 2 should be no more than twice as thick as the foregoing wire section 1 and, at least when cutting is accomplished with round wires section having no kinds of saw teeth, the diameter of each subsequent wire section should preferably not be chosen larger than 50% above the diameter of the next foregoing wire section in the same cut.
  • FIG. 6 finally shows how the two wires section 1 and 2 may be imparteda longitudinal movement during the cutting operation by being each .continuouslyfed between a pair of storage dr-ums 11 and 12 respectively over-suitable pulleys 13. Also with the arrangementof FIG. 6 it.will obviously be possible to feed the two wiressection land 2 either in opposite longitudinal directions or in one and the same direction, the'direction of movement of each wire section being, however, unchanged throughout theqentire cutting process, which is contrary to the case of FIG. 5.
  • eachfollowing wire section is thicker than the next preceding wire section that has passed through the same cut, including the first cutting wire section.
  • each thicker following wire section is no more than twice as thick as the next preceding wire section in the same cut.
