Definitions

  • the present invention relates to a method and apparatus for creating fold lines when bending corrugated sheet transversely of the corrugations.
  • the invention is intended preferably for application in the building construction field for roofing purposes and in the construction of industrial buildings and storage locations, tool sheds, etc., in such cases as those where the walls of said building structures are also covered with corrugated sheet.
  • the inventive method can also be used advantageously in other fields, for instance in the provision of corrugated sheet surrounds for loading pallets.
  • corrugated sheet cannot be bent transversely of its corrugations without great difficulty, it is endeavored to avoid such constructions, by placing joints at angled locations, where the sheets are placed at an angle to one an- other, and then covering the joints with an angled strip bent from flat sheet. Alternatively, one sheet can be allowed to project over the joint location, when possible. Consequently, there is a need to be able to bend corrugated sheet easily, for instance so that corrugated sheet can be placed over an arris or roof ridge, thereby eliminating the need for separate ridge plates.
  • sheds or similar, simple storage facilities an advantage would be gained if one and the same corrugated sheet could be extended from the roof of a building down onto a side wall thereof.
  • the object of the tongued pressfoot is to keep the sheet locked against the die preventing undesirable deformation of the sheet appearing as an increase in the dimensions of the sheet at the fold line.
  • This apparatus requires in order to enable pressing of fold lines in sheets having different types of corrugations that the apparatus is provided with a number of pressfeet having different positions of the tongues, alternatively that the tongues are arranged adjustable on the pressfoot. Changing the pressfoot and adjusting the tongues of the pressfoot respectively is time consuming and requires in the latter case a certain ability by the operator.
  • These apparatuses are preferably suited for stationary use as the force re- quired to keep the sheet pressed against the die often exceeds the force required to create the fold line.
  • the object of the present invention is to eliminate said disadvantages by providing on one hand a method for simplifying the making of a fold line on a corrugated sheet transversely of its corrugations and on the other hand a more easy to handle and additionally less force requiring apparatus for carrying out the method. This is achieved by means of the method and the apparatus the characteristics of which appear from the following claims.
  • figure 1 shows the principal for making a fold line ' and the required apparatus in a side view
  • figure 2 shows figure 1 including further details
  • figure 3 shows a complete apparatus in a front view
  • figure 4 shows a plain view of the section A-A in figure 3.
  • FIG. 1 The principal according to the invention for making a fold line appears from figure 1.
  • a die 2 included in an edging press is here shown on which a corrugated sheet 4 is placed.
  • a pressbar 1 also included in the edging press provided with a rounded edge is moved towards the die under great force, by means of hydraulic pistons or by suitable equivalent means.
  • the fold line or weakening obtains the form of an indent 3 in the crests of the corrugations in the sheet 4.
  • the depth of the indent can be varied and therewith adapted to the angle to which the sheet shall be bent in a second stage, by adjusting the length of stroke of the pressbar.
  • FIG 2 shows in a front view a complete apparatus including a frame 12 the lower bar of which is constituted by the die 2 and at the upper bar 13 of which hydraulic pistons 11 are arranged to press " by means of their piston- rods 14 the pressbar 1 against a sheet 4 positioned on the die which sheet is fixed between the locking means 5, 6.
  • FIG 4 a section A-A through the apparatus according to figure 3 is shown in a plane view with the corrugated sheet 4 fixed on the die 2 between the locking members 5, 6.
  • the locking means are provided with two planes perpendicular to each other one of which 8 is arranged vertically and is intended to bear against the side of the sheet and is provided with a recess 7 which al- lows the pressbar to pass in its movement.
  • the locking means is in view of fixing the sheet intended to be displaced along the upper surface of the die whereby its second plane 9 bears against the die and could be locked against the die by means of screws 10.
  • a sheet provided with one or several fold lines can be transported and handled as untreated sheet and be bent to a desired angle in the second stage with the aid of simple means over the edge of a workbench or some like support.

Abstract

L'invention concerne un procédé et un appareil permettant de créer sur des tôles ondulées des pliures transversales aux ondulations pour pouvoir, lors de l'opération suivante, couder la tôle avec l'angle de courbure souhaité. Selon ce procédé, la tôle (4) est serrée entre deux moyens de blocage (5, 6) placés sur le coussin (2) d'une presse à plier ou équivalent et une pliure est créée sous la forme de plis au sommet des ondulations au moyen d'une barre (1).
