Embodiment Construction

[0012] Figure 1A Schematically shows a cross-sectional view of a cutting device for cutting a strip from a material web, in particular an unvulcanized rubber strip, more particularly a cord-reinforced material strip.

[0013] The cutting device is provided with an elongated upper blade 1 and a lower blade 2 capable of moving along the elongated upper blade 1 . The lower blade 2 is a rotatable, at least approximately circular blade having a beveled cutting edge 3 oriented towards the upper blade 1 .

[0014] The elongated upper blade 1 is able to pivot until it comes into at least substantially abutting contact with the lower blade 2 , said oscillation including at least a component transverse to the elongated upper blade 1 . In the embodiment shown in FIG. 1 , the upper blade 1 is capable of swinging around a rotation axis 4 parallel to the longitudinal direction of the upper blade 1 .

[0015] The swing of the upper blade 1 is realized by means of an electric motor, specif...

Abstract

Method for manufacturing a tyre from spliced strips, wherein the first strip is cut and the strip is placed on a discharge conveyor. After cutting the first strip a second strip is cut and placed on the discharge conveyor. After that the first and second strip are spliced. Between cutting the first strip and placing the second strip on the discharge conveyor the second strip is retained over the discharge conveyor, the projected separation distance between an end of the first strip and an end of the second strip to be spliced to said end is measured, and based on the measured separation distance the first strip is relatively displaced such with respect to the second strip that the end of the first strip is placed in the wanted position with respect to the second strip, after which the second strip is placed on the discharge conveyor.

Description

Background technique [0001] The invention relates to a method for the manufacture of tires of spliced ​​strips of rubber material, in particular unvulcanized rubber material, more particularly cord-reinforced rubber material, wherein the method is used for A cutting device for cutting strips from a material web, the cutting device being provided with a discharge conveyor for unloading the strips, and a splicing device for splicing the cut strips, the method comprising the steps of: [0002] - cutting a first strip from the rubber material strip and placing this first strip on the discharge conveyor, [0003] - after cutting the first strip, cut the second strip from the rubber material strip and place the second strip on the discharge conveyor, [0004] - After having placed the first and second strips on the discharge conveyor, splicing the first and second strips to produce a spliced-strip tire. [0005] Such a method is known from EP-A-2.125.304. In this case, the ends o...
