Method and device for manufacturing polyurethane products, in particular day marks for buoys.

摘要

The invention relates to a method for pouring polyurethane into a mould (100). In a first step a distributing device (1) is disposed close to the mould. The distributing device comprises a housing (2) provided with a feed (3) for polyurethane and with two or more discharges (4A;4C) which are adapted to deliver polyurethane at two or more spatially separated positions. Polyurethane is fed to the distributing device. Using the discharges the supplied polyurethane is delivered to the mould at the two or more spatially separated positions. The invention also relates to a distributing device (1) for application in the method. In a preferred embodiment of the invention, the length of the delivery means (14A,B,C,D) are adjusted to the filling height of the mould (100) in order to deliver the polyurethane close to the bottom. In a further embodiment of the invention, the combined outflow area of the discharges (4A,C) is greater then the inflow area of the feed (3).
