Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
93 words
A method of manufacturing slide fasteners in combination with the steps of gapping an elongate continuous stringer chain (F) to provide element-free space portions (T′) at predetermined intervals therealong, applying various fastener component parts to said stringer chain (F) and cutting said stringer chain (F) into individual slide fastener products (F', F˝), characterized in that said method comprises metering said elongate continuous stringer chain (F) to provide different prospective slide fastener product lengths and maintaining a provisional inventory of the thus metered lengths of the stringer chain (F) in advance of said gapping.
Claim 2
Independent Claim
93 words
A method of manufacturing slide fasteners in combination with the steps of gapping an elongate continuous stringer chain (F) to provide element-free space portions (T′) at predetermined intervals therealong, applying various fastener component parts to said stringer chain (F) and cutting said stringer chain (F) into individual slide fastener products (F', F˝), characterized in that said method comprises metering said elongate continuous stringer chain (F) to provide different prospective slide fastener product lengths and maintaining a provisional inventory of the thus metered lengths of the stringer chain (F) in advance of said gapping.
Claim 3
Dependent Claim
19 words
A method according to claim 1 characterized in that said stringer chain (F) is one and the same type.
Claim 4
Dependent Claim
25 words
A method according to claim 1 characterized in that said stringer chain (F) consists of a plurality of different types of interconnected groups of stringers.
Claim 5
Dependent Claim
68 words
An apparatus carrying the method of claim 1 into practice which comprises a metering means (16) of metering said stringer chain (F) to provide different prospective slide fastener product lengths and a reservoir (V) for maintaining a provisional inventory of the thus metered lengths of the stringer chain (F), both of said metering means (16) and said reservoir (V) being located upstream of the position of said gapping.
