Definitions

  • the present invention relates to a lamella for forming a sipe in a pattern block of the tread band of a pneumatic tire
  • the lamella includes a first side wall and a second side wall parallelly arranged to each other, and a projection opposite a recess arranged on the other side wall is arranged in each side walls, having a surface geometry similar to a surface geometry of said recess, and said recesses are formed as channels and said projections are formed as ribs, and the side walls are roughened surfaces having congruent surface geometries to each other provided by a pattern consisting of chan- nels and ribs.
  • the invention further relates to a tyre having a sipe produced by said sipe forming lamella, as well as a method for forming said lamella.
  • Tread band pattern of tyres generally consists of blocks delimited by channels therebetween.
  • the role of the channels is to remove materials endangering good surface adherence from surface underneath the tread band rolling on wet, muddy or corny etc. road surface. Since this aim cannot be achieved perfectly by the channels alone, further smaller channels, so called sipes are formed in the blocks contacting the road surface just cleaned partially. The purpose of these sipes is to remove mud and water still remained on the road surface contacting the blocks, preventing the vehicle from sliding on the wet surface (aquaplaning).
  • Sipes are narrow recesses having a width be- tween 0,2-1 ,2 mm, in general.
  • Sipes are formed by means of lamellas for forming a sipe arranged on the inner surface of tyre vulcanizing moulds.
  • Sipe forming lamellas of different shape, number and size are to be designed and placed in the tread forming pattern of the vulcanizing moulds according to different use (summer, winter, all seasons etc.) of tyres.
  • direct, meandering or curved thin recesses might be observed on the tread band of the tyres having a width of 0,4-1 ,2 mm.
  • the more the number of lamellas and thus sipes the better the adherence of the tyre is, since the number and size of grasping edges increases.
  • Lamellas consist of a mounting area to be inserted in a recess arranged in the wall of vulcanizing mould, and a sipe forming area having a shape of a sipe to be formed in the tyre. While tyre is rolling, sipes are strained on contacting the ground. In this state the a conventional sipe having smooth inner surfaces become fully closed and water excluded therefrom. Nevertheless, thin cuts having flat inner surfaces weaken rigidity of tread ban patterns. Especially, a winter pattern can be extremely articulated with 5-6000 sipes cutting the surface of the pattern into small, moving parts. Thus, expected strength of the pattern block decreases and risk of both breaking off and rapid chafing thereof are increased.
  • a response to this problem is using a so called 3D (three dimensional) lamella having an advantage of not only snagging the inner walls of the sipe, but also pressing elements of the 3D arrangement perpendicular to the walls into each other while the material of tyre compacted during running. Since the width of the sipe is equal to the thickness of the lamella, there is a distance of one-sipe-width between the convex part and the concave part of the elements shaped on the sheet of the lamella, which delimits the extent of sliding of the inner walls of the sipe on each other, thus, a deformation of the gum block is decreased. Consequently, the risk of both breaking off and rapid chafing of the pattern block is decreased.
  • a further disadvantage of this solution is that the mould opening after vulcanization be- comes very difficult to do, because several !amellas and its 3D elements form a huge undercut surface grasping by great force the just vulcanized tyre, therefore, the material gum components of the patterned tread band must be selected so as to get a soft surface in order to withstand the high deformation.
  • the exaggerated softness results in a rapid chafe.
  • Patent document JP2003118322 discloses a pneumatic tire provided with a tread pattern in which at least one sipe is formed in the block or a rib, the sipe has a corrugated part in which a wave length is gradually lengthened from a tire surface side to a deepest part side of the sipe or a zigzag part.
  • the mould opening force can be decreased by applying this solution, but opposing even inner surfaces of the sipe closing one to another continue being shifted more and more towards the bottom of the sipe allowing deformation of the pattern block resulted in fatigue and break off of the block.
  • the object of the present invention is to provide a lamella for forming a sipe which does not put a check on tyre production due to the lack of any substantial undercut, so that it decreases opening force required to open the vulcanizing mould in contrast with the prior art solutions, enabling to produce tyres having sipes and suitable hardness at once, decreasing maintenance time for the vulcanizing mould, and a sipe produced by applying said lamella decreases at the least, but preferably eliminates de- formation occurred due to the inner shifting of the sipe by preventing the inner walls of the sipe from shifting on each other while contacting the surface of the pattern block containing a sipe and the ground surface.
  • a further object of the present invention is to provide a tyre provided with sipes produced by applying lamellas according to the invention.

Because the surface geometry of each channels 8a and opposite ribs 9a are congruent, the tightly gripped channels 8a and opposite ribs 9a prevent the inner walls 6a, 7a of the sipe 4 from shifting on each other.
  • the distance between two respective surface points P6.P7 of a channel 8a and opposite rib 9a is constant and greater than the height of the rib 9a, therefore, the surface of a channel 8a and that of the opposite rib 9a in a part of the tyre 1 not contacting the ground cannot contact each other even in case of elastic displacement of the walls 6a, 7a.
  • This contact is achieved exclusively by contacting the ground a region of the block 3 surface surrounding the sipe 4. This way the stability of shape of channels 8a and ribs 9a will be increased during whole lifetime of the tyre 1 in- fluenced neither by the abrasion of the tyre 1.

  • Vulcanizing process of the tyre 1 provided by sipes 4 according to the invention can be achieved by using lamellas 5 for forming a sipe 4 having a part extending onto the vulcanizing cavity of the vulcanizing mould, which is formed according to the cavity of the sipe 4 to be created.

  • a vulcanized tyre 1 can be removed more easily from the mould, because the tyre 1 can be pulled from lamellas 5 having a finely roughened surfaces, instead of elements K,M of the prior art lamella L grasping heavily to the rubber of the tyrel .
  • a further advantage is that using the lamellas 5 according to the invention the vulcanizing mould can be opened after a shorter vulcanizing time due to a smaller mould opening force needed, because the opening force must be less than a force causing a damage of the tyre 1. This way the production ration can be increased, re- suited in decreasing of production costs and energy consumption, therefore, this is an environmentally friendly solution. Nosiness of the tyre 1 is also reduced, since the displacement of the grasping elements of the tread band 3a is decreased as well.
  • sipes 4 according to the present invention cannot displace substantially due to its roughened, knurled pattern.
  • the solution according to the invention is cheap and simple to apply. Abrasion of the tyre 1 and the risk of breaking off the pattern block 3a will be reduced. Therefore, the service time of the tyre 1 according to the invention is increased, that is the value of the tyre 1 will be higher as well.
