Device for metering and injecting a small amount of liquid into the splicing air of a compressed air thread splicing device with a plurality of splicing heads

摘要

Each splicing head (1) has its own compressed air metering valve (6). The supply pipes (7) of the compressed air metering valves (6) are connected to a collecting pipe (8). The collecting pipe (8) is connected to a liquid metering device (11) which is dependent on the amount of compressed air. The liquid metering device (11) ensures that a correctly prepared mixture of splicing air and liquid is supplied, in accordance with the removal of splicing air. Condensate forms inside the collecting pipe (8), the presence of which enhances the effectiveness of the device, however. IMAGE
