Abstract

PURPOSE:To enable homogeneous impregnation of a binder even into respective fine lines in the interior of a braid-like fiber unit by impregnating the binder into the above-mentioned braid-like fiber unit passing and running under a prescribed tension in a tilted tube having an outlet and inlet holes at both ends, wiping off the excess binder and continuously winding the resultant impregnated fiber unit. CONSTITUTION:A binder supply source 6 is communicated with a tubular unit 1 having an inlet hole 2 and an outlet hole 3 having a squeeze 4 for wiping off an excess binder arranged at both ends thereof and nip rolls 9 for regulating tension are simultaneously arranged in the tube. The tube is obliquely placed so as to provide the above-mentioned inlet hole 2 on the upper side. Thereby, a binder impregnating bath is constructed. A braid fiber unit 7 prepared by knitting fine wires into the form of a braid is inserted and passed through the afore-mentioned tubular unit 1 and impregnated with the binder 5 while regulating the tension to a desired value with the above-mentioned nip rolls 9. The excess binder is wiped off with the afore-mentioned squeeze 4 and the resultant braid is then continuously wound with a winding roll 8.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to structures with low tensile strength such as concrete and plastic; Structural materials used as a substitute for reinforcing steel or as a substitute for PCn4 wire, more specifically, for example, JP-A-131-2901
Disclosed in No. 50, thin wires are knitted into a braided cord shape, and each thin wire is bonded with a binder. This invention relates to a binder soaking bath for impregnating a fiber body with a binder.

(Prior Art) Conventionally, this type of binder impregnating tank consists of an open type binder impregnating tank main body a as shown in the second figure, and the binder impregnation [a binder tank is accommodated in the convex main body a, The braided fiber body C was continuously passed through the binder chamber. Note that d in the figure indicates a guide roller of the braided fiber body C.

(Problems to be Solved by the Invention) However, in the case of the conventional binder impregnation tank, there is a problem in that the binder does not sufficiently penetrate into the braided fiber body in which fine wires are knitted into a braided cord shape.

The purpose of this book is to provide a binder impregnating bath which can eliminate the above-mentioned disadvantages and allow the binder to sufficiently penetrate into the braided fiber body.

(Means for Solving the Problems) The binder impregnating tank of the present invention is a binder impregnating tank for applying a binder itself to a braided fiber body formed by knitting fine wires into a braided cord shape, A squeeze for wiping off excess binder is provided in the outlet hole of a freely insertable tubular body, a binder supply source is communicated with the tubular body, and the tubular body is arranged at an angle so that it faces toward the entrance hole or above. .

Moreover, a nip roll for tension adjustment may be provided within the tubular body.

(Function) The braided fiber body inserted into the tubular body from the inlet hole to the outlet hole absorbs a binder supplied from a source communicated with the tubular body while passing through the tubular body. The excess binder on the surface of the braided fiber body is wiped off with a squeeze for wiping off excess binder at the exit hole. Moreover, since the tubular body is arranged at an angle so that the inlet hole side is upward, the air contained in the braided fiber body moves upward and is degassed and defoamed.

(Example) Hereinafter, one example of the binder impregnation tank of the present invention will be described with reference to the attached drawings.

In the figure, reference numeral 1 indicates a tubular body made of an iron pipe, and the tubular body 1 is arranged at an angle so that the inlet hole 2 side faces upward, and the outlet hole 3 of the tubular body 1 has a squeeze 4 for wiping off excess binder. A supply source 6 of a binder 5 such as epoxy resin, for example, consisting of a binder supply tank is connected to the inlet hole 2 side. In the illustrated embodiment, the entrance hole 2 side of the tubular body 1 is bent in a substantially horizontal direction so that the braided fiber body 1 impregnated with the binder 5 can be pulled out from the entrance hole 2 in a substantially horizontal direction. In the figure, reference numeral 8 indicates a winding roll, and as the braided fiber body 7 is wound in the direction of the arrow and the winding radius increases, the braided fiber body 7 is lowered downward as shown by the arrow. The take-up angle was made constant. Further, in the illustrated embodiment, a tension A adjusting nip roll 9 is provided in the tubular body 1, and the tension applied to the braided fiber body 7 by the winding roll 8 is adjusted to a desired value, and the binder 5 is It was made to be impregnated into the fiber body 7. Although not particularly shown, the tension adjusting nip roll 9 may be provided outside the tubular body 1.

Next, to explain how to use the binder impregnating tank, first, the braided fiber body 1 is passed through the tubular body 1, and the tension is adjusted to the desired tension by the adjusting nip roll 9 while being wound up by the winding roll 8. While adjusting and continuously taking off the binder 5
is supplied into the tubular body 1 from a supply source 6, and the braided fiber body 7
While passing through the tubular body, each thin wire constituting the braided fiber body 7 is impregnated with the binder 5. Excess binder on the surface of the braided fiber body 7 impregnated with the binder 5 is wiped off with a squeeze 3 for wiping off the excess binder provided in the inlet hole 2,
The braided fiber body 1 impregnated with a binder is continuously wound onto the winding roll 8 .

(Effects of the Invention) As described above, according to the binder impregnating tank of the present invention, the braided fiber body inserted from the inlet hole to the outlet hole of the tubular body is attached to the tubular body while passing through the tubular body. The tubular body 5 is impregnated with a binder supplied from a connected supply source, and the excess binder on the surface of the braided fiber body is wiped off with a squeezer for wiping off the excess binder. Since the braided fibers are arranged at an angle, the air contained in the braided fiber body is degassed and degassed, and each thin wire in the braided fiber body is impregnated with the binder.

Further, when a tension adjusting nip roll is provided in the tubular body, the tension of the braided fiber body is adjusted to a desired value, and the binder is impregnated in an optimal impregnated state.
