Description
Известны способы изготовлени однослойных изделий из бумажной массы с применением сетчатых матрицы и контрматрицы, включаемых в вакуумную коммуникацию.Methods are known for producing single-layer articles of paper pulp using a grid matrix and countermatrices included in vacuum communication.
Описываемый способ изготовлени литых изделий из бумажной массы позвол ет получить двухслойные издели . Дл этого обе части формы погружают в бумажную массу и осаждение ее осуществл ют раздельно на матрице и контрматрице с образованием за один прием при прессовании двухслойного издели .The described method for producing molded articles from paper pulp allows to obtain two-layer products. To do this, both parts of the form are immersed in the pulp and deposition is carried out separately on the matrix and countermatrix with the formation of a two-layer product at one time during pressing.
На чертеже изображен продольный разрез устройства дл осун|ествлепи способа.The drawing shows a longitudinal section of the device for carrying out the method.
Формз. состо щую из матрицы / и контрматрицы 2, имеющих трубопроводы 3 1 4, соедин емые с вакуумной коммуникацией, погружают в бумажную массу 5. Осаждение слоев бумаги осуществл ют раздельно на матрице, и на контрматрице..Formz. consisting of a matrix / and a countermatrix 2, having pipelines 3 1 4, connected with vacuum communication, is immersed in a paper pulp 5. The deposition of paper layers is carried out separately on the matrix, and on the countermatrix ..
По мере образовани слоев 5 и 7 бумажной массы на сетчатых стенках матрицы и контрматрицы, последние смыкаютс и прессуют изделие с одновременным подн тием его из ванны. После запрессовки издели матрица опускаетс в ванну, а двухслойное изделие снимают с коптрматрицы.As layers 5 and 7 of the paper pulp form on the grid walls of the matrix and the countermatrices, the latter are closed and pressed the product while simultaneously lifting it from the bath. After the product is pressed in, the matrix is lowered into the bath, and the two-layer product is removed from the coptermatrix.
Предмет изобретени Subject invention
Способ изготовлени изделий из бумажной массы путем отливки е применением форм, включаемых в вакуумную коммуникацию и состо щих из матриц с контрматрицами, отличающийс тем, что с целью получени двухслойных изделий, осаждение слоев бумажной массы осуществл ют раздельно как на матрице, так и на контрматрице , после чего слои прессуют и снимают с форм.A method of manufacturing articles of paper pulp by casting using molds included in vacuum communication and consisting of matrices with countermatrices, characterized in that in order to obtain two-layer products, the deposition of layers of pulp is carried out separately on the matrix and on the countermatrix, after which the layers are pressed and removed from the forms.
