HERSTELLUNGSVERFAHREN VON FORMEN FÜR SPIKEREIFEN

摘要

#CMT# #/CMT# The method involves forming a mold liner (G) by arranging strips (L1-L6) with equivalent lengths, on liner parts that mold tread blocks, and radially disengaging a thermosetting material (T) of the liner and the strips in a cylindrical space situated at the level of places receiving pins that mold housings of spikes. A removable insert that supports the pins, is arranged in an orifice that is obtained by laser method or spark-machining. #CMT# : #/CMT# An independent claim is also included for a tire formed with a mold liner. #CMT#USE : #/CMT# Method for forming a mold liner to manufacture a tire (claimed) of a terrestrial vehicle moving on ground e.g. slippery ground, icy ground and snowy ground. #CMT#ADVANTAGE : #/CMT# The method permits to form the mold liner to manufacture a tire, in a simple and inexpensive manner. The removable insert permits to replace the pin during usury or broken, in an easy manner. The method permits to form marking patterns on a surface of the insert for ensuring aesthetic nature of the tire. The method can be adapted to form any type of mold. The method permits to avoid the strips to be deformed under an action of a drill bit and vibration. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional front view illustrating a step of piercing a mold liner. D : Determined diameter F : Monoblock drill bit G : Mold liner L1-L6 : Strips T : Thermosetting material.
