AI Technical Summary

Problems solved by technology

Troublesome disassembly work is required for this
Furthermore, in the production of synthetic filaments it is usual to hold several spinneret packs and spinning pumps on one spin beam, which has the disadvantage that each of the spin pumps attached to the spin beam has to be assigned A separate heating mechanism is provided to regulate the temperature of the melt guide part
This makes it almost impossible to avoid temperature differences

Embodiment Construction

[0026] exist figure 1 with 2 A first embodiment of the device according to the invention is shown in several views. figure 1 This embodiment is shown schematically in cross-section, while in figure 2 This embodiment is shown in a top view in the figure, and the following description applies to both figures as long as reference is not specifically made to a certain figure.

[0027] This embodiment of the device according to the invention has a spinning beam 1 and a pump support 2 which are arranged parallel to one another.

[0028] Such as figure 2 As shown in , the pump support 2 extends substantially parallel to a longitudinal side of the spin beam. A plurality of spinneret packs 3 are held in a row on the spinning beam 1 . In the present embodiment, the spinneret packs 3 are each formed from a rectangular spinneret.

[0029] A plurality of spinning pumps 17 are also held in a row-like arrangement on the pump support 2 extending alongside the spinning beam 1 . Here, ...

Abstract

The invention relates to a device for melt-spinning synthetic filaments, comprising a spin-die manifold for holding at least one bank of spinnerets and heating means for heating the bank of spinnerets. At least one spinneret with second heating means for heating the spinning pump is allocated to the bank of spinnerets and the spinning pump and bank of spinnerets are interconnected by a melt line. To achieve the most user-friendly arrangement possible for the bank of spinnerets and the spinning pump, said pump and the second heating means are held by a separate pump support which is placed at a distance from the spin-die manifold. This allows the spinning pump to be heated independently of the spin-die manifold.

Description

technical field [0001] The invention relates to an apparatus for melt spinning synthetic monofilaments according to the preamble of claim 1 . Background technique [0002] A device of this type is known from WO 2005 / 123994 A1. [0003] The known device consists of a spin beam which holds on its underside a plurality of spinneret packs arranged in a row. For heating the spinneret pack, the spinning beam forms a heating chamber which surrounds the receptacle of the spinneret pack in the interior of the spinneret pack. A spinning pump is arranged on the upper side of the spinning beam, which is fastened to the upper side of the spinning beam by means of a pump connection block. The spinning pump is equipped with a heating device which surrounds the spinning pump with a heating medium in the form of a heating jacket. Here the spinning pump is formed by a multi-stage pump and is connected to the spinneret assembly through a plurality of melt pipes. In practice, the pump conne...
