Splicing passage unit with specially configured inlet passage for splicing air, splicer with such splicing passage unit and textile machine with such splicer

摘要

The invention relates to a splice channel unit, a splicer and a textile machine. Here, air inlet ducts (660, 66u) are especially designed to be a splice channel (20) injecting splice air into the splice channel unit (60). According to specific variants of the splice channel unit, the splice channel unit has a) the minimum of the length l of a portion (69o, 69u) near outlets and the minimum of the diameter d of the outlets (70o, 70u) communicated with the splice channel (20), b) a value of the ratio rld=l/d exceeding the minimums, wherein the portion (69o, 69u) near the outlets must basically not have structures which may prevent the splice air from flowing under the condition a) and the condition b), or c) the air inlet ducts (660, 66u) designed to enable the splice air to form a laminar flow imported to the splice channel (20) before the outlets (70o, 70u) of the splice channel (20) of the air inlet ducts when the splice air flows through the splice channel.
