Definitions

  • the invention relates to an edge protector for rollers according to the preamble of patent claim 1.
  • the primary focus here is on rolls that are created by rolling up paper or aluminum webs, e.g. such a roll of paper web can have a diameter of about 1.5 m.
  • the edge protection to be created could also be used in general for rolls or rolls of any kind, which consist of a solid material.
  • An edge protection of the type mentioned at the outset is known from US-A-1,989,182.
  • the disc lies between a roller end face and the tabs of a web strip; the tabs are extremely. Since the tabs have the tendency to spring open (resilience), that is to say to assume the position of the rest of the web strip, a tensile force is constantly exerted on the second adhesive layer of the tabs.
  • the adhesive begins to pull apart and, after a certain storage time, the flap opens one after the other.
  • Disadvantages are, on the one hand, the loading of the second adhesive layer on tension and, on the other hand, the fact that the pane itself cannot exert any supporting effect on the large number of tabs against its opening.
  • the aim is to create an edge protector in which this disadvantage can be avoided.
  • the pane is now extremely out; ie the tabs are between a roller end and the disc.
  • the aforementioned resilience of the tabs (the tendency to crack open) is now exerted a compressive force on the second adhesive layer; ie the tabs constantly press against the pane.
  • This pressure load on the second adhesive layer is advantageous since it then does not endeavor to pull apart.
  • the disc exerts an external force acting on the plurality of tabs, so that the tabs are also prevented from opening.
  • the material for the two components namely the web strip, which adheres to the outer surface of the roll and protrudes beyond the edge of the roll in its end face, and the second component, namely the disc, which lies on the end face of the roll and adheres to the first component consist of the same material.
  • a simple, cheap and effective material is e.g. Corrugated cardboard in sandwich construction, whereby a middle corrugated layer adheres to flat layers with its corrugated combs on both sides. Such a material is cheap, can be processed well and can cushion the edge of a roll well and thus protect it from damage.
  • the invention further relates to a material web from which the first component of the edge protector can be produced inexpensively.
  • the invention further relates to a method for producing such a first component of the edge protection from this material web.
  • the disc 2 lies on the end face of the roll (FIG. 5), and the web strip 1 partly lies on the outer surface 3 of the roll 4 and partially at its end face 5.
  • the length profile of the web strip 1 has been designated by the double arrow A in FIGS. 2 and 3.
  • the web strip 1 has the width B.
  • the length profile A is divided into two longitudinal webs, namely a first longitudinal web 6 and a second longitudinal web 7.
  • FIG. 2 is intended to represent the outside of web strip 1 and FIG. 3 then shows that Inside of this lane. From Figure 3 it can be seen that the first longitudinal web 6 has on its inside a first adhesive layer 8, which is shown with a dot hatch.
  • the second longitudinal web 7 has on its outside a second adhesive layer 9, which is also shown with dot hatching.
  • This adhesive layer 9 is also covered with a second cover film, not shown, but it will be explained in detail in a manner explained later that the cover film is only present in the areas hatched in FIG. 2.
  • the first adhesive layer 8 is not visible in the illustration according to FIG. 2, since it is located at the bottom.
  • the second adhesive layer 9 is not visible, since it is also at the bottom.
  • the first and second adhesive layers 8 and 9 lie directly next to one another in the transverse direction of the web strip 1. It should be noted that, in another embodiment, the two adhesive layers 8 and 9 can also be spaced apart.
  • the second longitudinal path 7 is formed from tabs 10 which extend from the first longitudinal path 6 in the transverse direction of strip 1 protrude.
  • the tabs 10 are triangular.
  • the second component of the edge protector designed as a disk 2 has a slightly smaller diameter than that of the roller 4, as shown in FIG.
  • the disc 2 has an opening 11 in the center through which a rod for the transport of the roller 4 can be inserted.
  • the disk could also be designed as an annular disk in another exemplary embodiment, so that it would then only cover a small part of the end face of the roller 4.
  • the web strip shown in FIGS. 2 and 3 is supplied ex roll, whereby the web strip 1 in the illustration according to FIG. 3 is placed on the outer surface of the roll 4 in its edge region (after the first cover film mentioned has been removed), so that then the first adhesive layer 8 adheres to the outer surface 3 of the roll, so that the tabs 10 protrude beyond the end face of the roll 4.
  • the second longitudinal web 7, ie the tabs 10 are angled approximately at right angles to the first longitudinal web 6, so that the tabs 10 come to lie approximately in the end face of the roller 4, according to the right-hand side in FIG. 4.
  • this second cover film with its tab-shaped sections can be formed in one piece, so that only a single second cover film in FIG. 2 has to be removed in order to expose all hatched areas, that is to say the second adhesive layer 9.
  • the pane 2 is pressed against the end face of the roller 4, so that the pane 2 adheres to the second adhesive layer 9 in the edge region, according to FIG the left side in Figure 4.
  • an edge protector has been attached to an edge of the roller 4.
  • the web strip 1 shown in FIG. 2 has been bent at a right angle approximately in the region of the bending line 12 and protects this roll edge.
  • the second longitudinal web 7 as tabs 10
  • rolls of very different diameters can be reliably protected in the same way in the edge region with one and the same web strip, since depending on the diameter of the roll 4, the tabs 10 in the position according to FIG. 4 simply more or less to be closely approximated.
  • the second component that is to say the pane 2
  • the first component that is to say the web strip 1; however, different materials could also be used.
  • the corrugated cardboard mentioned at the beginning has proven itself for both components.
  • Such a material web 13 shown in FIG. 1 is made into two at the same time by punching (apart from a few common target tear points 15) Web strip 1 formed by punching with a knife, not shown, with a zigzag cutting edge according to the contour 14.
  • the first adhesive layer 9 is cut through together with the cover film adhering to it and the entire material of this material web 13, so that two web strips 1 are formed in one operation, which are therefore only connected by a few common target tear points 15 and when using an edge protector be torn from each other at these points 15.
  • the finished web of material according to Figure 1 is rolled up and is sold. To make it easier for the person to separate the required length from the roll material when in use, it is expedient if the material web 13 is provided with a marking for the running meter (or half a meter) along the length course A, specifically for both web strips 1.
