  • a hardness value Shore less than 90, preferably Shore less than 85 and more preferably Shore less than 82 is favorable, whereby a lower limit in the range of Shore 75 can be regarded as favorable.
  • a gutter leg of the gutter profile according to the invention should have an inner rib projecting towards the gutter space, from which a cross-sectionally part-circular inner contour of the gutter space originates, that is to say an undercut lateral region of the latter.
  • this inner rib of the rib leg is opposite an inner rib of the other gutter leg - also as a holding member for the insert profile - opposite;
  • These inner ribs together define an undercut area of the channel space in the channel profile.
  • the side surfaces of the insert profile preferably extend at an angle to the center line of the cross section and are each provided at one end with a side rib.
  • the bottom surface of the insert profile assigned to the two side ribs should be associated with the inner surface of the channel profile under bending of the molding strip.
  • the shaped strip of small thickness is integrally formed with its edge regions on mutually opposite side surfaces of the channel profile on the one hand and of the insert profile on the other hand.
  • the forming strip facing side surface of a gutter leg of the gutter profile two at an angle - preferably from about 130 ° to 140 ° - mutually extending console surfaces which form between them a kind of excellent construction line.
  • the mold strip connecting the channel profile and the insert profile is preferably formed on the desk surface near the free end of the channel leg.
  • the shaped strip is integrally formed on the side profile of the insert profile adjacent to the gutter profile; the side surfaces should run at a slight angle to the center line of the insert profile cross-section and are each provided at one end with a side rib.
  • the sheet 10 shows the contours of eight contiguous blanks 12 for cartons; by these blanks 12 cyclic punching operations are expected to arise and point - the subsequent folding process predefined - creasing lines 14 on and outside limiting cutting lines 16 as punched contours. Adjacent cutting lines 16 are so-called by pairs. Breakpoints 18 connected; the latter are required for further transport of the punched sheet 10 a punching tool 20.
  • the cardboard or corrugated board sheet 10 below a support plate 22 of the thickness a of the punching tool 20 according to Fig. 2 a punching plate 24.
  • the carrier plate 22 consists of a multi-layered plywood plate, in which 30 laser cuts 26 have been introduced in an arrangement corresponding to the contours of the intended packaging for receiving punching knives as so-called. Knife or cutting lines; In many cases, several packages - up to fifty or sixty - are arranged in groups on such a cardboard or corrugated board 10.
  • the punching blade 30 of the exemplary thickness b of 0.7 mm, the height e of here 24 mm and the length f of approximately 60 mm on its cutting edge 28, which is designated as a knife or cutting line, is arranged at a distance i from one another - Notched indentations or interruptions 29 of length n, for example, 1 mm, which determine in a sheet 10 formed in the cutting line 16 those breakpoints 18.
  • the protruding from the plywood plate 22 section of the punch blade 30 is flanked on both sides of - made of metal, in particular light metal, rigid plastic or ceramic - groove profiles 34 of height c of about 2 mm.
  • the width q of the channel profiles 34 here measures about 12 mm.
  • the channel legs 35 of the plywood board 22 bonded by an adhesive layer 33 channel profile 34 define a channel space 36 and are in Fig. 2, 4 cross-section on the inside - with formation of a respective lateral undercut region - curved to provide the cross-sectionally shaped ridge region 38 of a rubber profile 40 almost rectangular cross section of the free height h clamping stop.
  • the profile side surfaces 42 are away from the ridge portion 38 a little cross-section curved toward the profile center line M and down further outwards, so that near the profile base surface 44 on both sides a kind of diligentwulst 43 is formed.
  • the base surfaces 44 of the rubber profiles 40 which are guided in the pressure direction x, lie on the sheet 10 (on both sides of the corresponding punching contour 16), changing the profile cross section. Fig. 4 ).
  • enormous wedging forces which destroy the holding points 18, occur.
  • the cross section of the rubber profile 40 is in this case selected so that in addition act forces to the punching blade 30 out.
  • the rubber profiles 40 seated in the exemplary glued-on (alternatively: inserted or pressed into suitable cutouts) channel profiles 34 are easy to remove again and can be traced back. Also, a quick change to others - e.g. softer - rubber materials possible.
  • An inventive groove profile 50 made of elastomer, rubber or a rubber material of a Shore hardness according to DIN 53 505 between 60 and 90 g of the width g of about 10 mm and the free height k of about 3.5 mm of its two of a bottom plate 52 projecting Trough legs 54, 58 is in Fig. 5 outlined.
  • the left-hand gutter leg 54 forms a side plate 53 of the channel profile 50 which is rectangular relative to the bottom plate 52 and has a part-circular inner contour 53a which forms an inner rib 56 with a likewise part-circular end region 55 of the channel leg 54.
  • the other channel leg 58 adjoins that bottom plate 52 with an outer panel surface 57 and also has a part-circular inner contour 59a towards the channel space 62, which also merges into an inner rib 64.
  • the inner ribs 56, 64 define an undercut region 63 of the groove space 62 (FIG. 2) with the part-circular inner contour 53a or 57a respectively adjoining them. Fig. 6 ).
  • the above-mentioned panel surface 57 includes cross-sectionally at one end to the outer surface 51 of the bottom plate 52 and the other end to an endskyrtige desk surface 59 which forms an angle w of about 135 ° with the outer panel surface 57 and merges into a part-circular end portion 55 a.
  • FIG. 5 At a distance from the channel profile 50 this is in Fig. 5 assigned an insert profile 70 almost rectangular cross-section and connected to it by a molding strip 60 of small thickness b1; the latter is formed on the one hand on the endracertige desk surface 59 of the channel profile 50 and on the other hand on a side surface 68 of the insert profile 70 of the height k1.
  • These side surface 68 emanating from the ridge surface 72 of the insert profile 70 and the other side surface 69 of the insert profile 70 extend inwardly toward the profile center line Q at an angle t of approximately 10 ° and in each case transition into a side rib 74 or 76 of the insert profile 70.
