Abstract
Abstract 1,191,701. Attaching spouts to webs. UNION CARBIDE CORP. 21 April, 1967 [21 April, 1966], No. 18544/67. Heading B5D. Spouts 12 to be attached to a web 16 are carried to the attaching station on the web itself. The spouts may be fed by a vibratory feeder 10 and may be guided during their motion on the web by a retractable arm 18 which terminates in a hook 20 locating the spout between welding devices 24, 28. In the form shown the web moves intermittently, but the web motion may be continuous, the welding members 24, 28 being then reciprocated so that they move with the spouts during the welding. The securing may be effected by a hammer blow, and the hammering device may be stationary and may act on the spouts while they are moving.
