Embodiment Construction

[0045] Next, the rubber material supply method of the first invention and the rubber material supply device 1 for implementing it will be described based on the drawings.

[0046] The rubber material supply method of the first invention includes a separation step S1 ( Figure 4 shown), processing step S2 ( Figure 5 shown) and input process S3 ( Image 6 shown).

[0047] in addition, figure 1 It is a side view showing a rubber material supply device 1 for implementing the rubber material supply method of the first invention, figure 2 is its top view. in addition, image 3 It is a side view showing the cutting tool 5 and the processing tool 6 of the rubber material supply device 1 .

[0048] Such as figure 1 , 2 As shown, the rubber material supply device 1 of this embodiment is used to supply a strip-shaped unvulcanized rubber material G from the front end GF in the longitudinal direction X to the rubber inlet 3A of the rubber extruder 3 .

[0049] The rubber extrude...

Abstract

Provided are a rubber material supplying method and a rubber material supplying device, whereby a rubber material can be smoothly supplied to a rubber inlet even when the width of the rubber materialis greater than the width of the rubber inlet. The rubber material supplying method includes a separation step S1, a processing step S2, and an input step S3. In the separation step S1, a plurality ofdifferent cutouts 30 are formed in a leading end section GF of a rubber material G, and the leading end section GF is separated into three or more band shape sections 31. In the processing step S2, second band shape sections B, and not first band shape sections 31A, among the plurality of band sections 31 are each cut out or folded. In the input step S3, the leading end section GF is input to therubber inlet 3A from the first band shape sections 31A.

Description

technical field [0001] The present invention relates to a rubber material supply device and a rubber extruder for supplying a strip-shaped unvulcanized rubber material from a front end in the longitudinal direction to a rubber inlet. Background technique [0002] Conventionally, there is known a rubber extruder which continuously extrudes rubber in a predetermined cross-sectional shape. A strip-shaped unvulcanized rubber material is supplied from a rubber material supply device to a rubber inlet of such a rubber extruder. The strip-shaped rubber material has a predetermined width. However, in some rubber extruders, the opening width of the rubber inlet may be smaller than the width of the rubber material, and there is a problem that the rubber material cannot be supplied into the rubber extruder. [0003] Therefore, in Patent Document 1 below, a rubber material folding device for reducing the maximum width of a strip-shaped rubber material is proposed. The device includes...
