Embodiment Construction

[0016] The flexible film article may be a glove or a condom or any other flexible film material formed on the former. In an exemplary embodiment, the invention is explained in terms of glove manufacturing. The invention is not limited to glove manufacturing processes.

[0017] During the glove manufacturing process, multiple formers are installed on the endless chain at equal intervals, and the endless chain moves along the guide rail at a constant speed. These formers are dipped into a first dip tank filled with coagulant material. The former then goes to a second dip tank filled with latex material. The formers were dipped into a second dip tank, and latex adhered to the surface of each former after removal from the second dip tank. The latex on the surface of each former is dried and cured. As a result, a flexible film article, such as a glove, is produced on the surface of each former. The glove is produced in a state of being adhered to the surface of the correspondi...

Abstract

An apparatus (10) for reducing noise level during stripping a flexible film article from a former comprises: a cylindrical body (5), having at least one inlet (7); a plurality of apertures (6), formedon the cylindrical body (5); a plurality of tubes (2), attached on the cylindrical body (5) through the apertures (6); and, a means for introducing compressed air into the article, wherein the compressed air is introduced through the inlet (7) is diverted via the tubes (2) to form a laminar air flow such that noise level is reduced.

Description

technical field [0001] The present invention relates to an air nozzle, and more particularly, to an air nozzle capable of reducing the noise level generated in a production line. Background technique [0002] In glove manufacturing, robotic arm strippers have greatly improved the noise level in glove manufacturing by using an open tube that sprays gloves with compressed air. Turbulent airflow is created when the fast-moving airflow from the open tube comes in contact with the surrounding static air. A by-product of this phenomenon is excessive noise. Due to this fast-moving air flow, gloves can tear when peeled off. Therefore, the quality of the manufactured glove is reduced. The typical sound pressure level at 1 meter from the nozzle can reach 105dB. Storage tank compressed air pressures typically range from 45 to 105 psi (300 to 700 kPa). Air acceleration varies from near zero velocity in the storage tank to peak velocity at the pipe outlet. The velocity of flow thro...
