Abstract
Abstract A band of foil is continuously pulled off a roll of the band and fed at a constant rate downwardly toward a station. The band is periodically deflected laterally from its path between the roll and the station so that the free end of the band in the station periodically stops completely. At the same time a succession of bottles is displaced transversely through the station, with one bottle being in the station each time the free end of the band stops. The free end of the band is pressed against the bottle in the station and is severed from the rest of the band each time the band stops in the station. Spots of adhesive are printed on the band on one face thereof upstream of the station and the deflector and advance rollers that engage this face downstream of the printing location only engage this face between the adhesive spots.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
376 words
An apparatus for making foil blanks from an elongated band on a roll and for applying said blanks to objects, said apparatus comprising: a pair of upstream rollers gripping said band; drive means connected to said upstream rollers for rotating same at a constant peripheral speed and thereby pulling said band off said roll at said speed and advancing said band downstream along a band path; means including a glue-applying roller downstream of said upstream rollers for applying adhesive to one face of said band in spots spaced apart on said one face transverse to the travel direction of said band along said band path; a pair of downstream rollers gripping said band downstream of said glue-applying roller, one of said downstream rollers engaging said one face only between said spots; means including a deflector engageable with said band between said glue-applying roller and said downstream rollers on said one face only between said spots for periodically deflecting said band between said upstream and downstream rollers perpendicular to said travel direction and thereby periodically stopping said band at said downstream rollers; means including a slip clutch between said downstream rollers and said drive means for urging said downstream rollers into rotation at a peripheral speed substantially greater than that of said upstream rollers and for permitting said downstream rollers to stop rotating completely when said band stops at said downstream rollers; means including a cutter operable synchronously with said deflector and downstream of said downstream rollers for cutting through said band when same stops at said downstream rollers, and thereby forming a blank; means operating synchronously with said cutter and deflector for conveying said objects through a station on said band path immediately downstream of said downstream rollers along an object path passing transversely through said band path at said station with one object being positioned in said station each time said band stops thereat; means including a holder engageable with the blank in said station and therethrough with the object therein for pressing said blank against said object when said band stops and said cutter cuts through said band; and means along said object path downstream of said station for wrapping said blank tightly around said object as same is transported away from said station.
Claim 2
Independent Claim

An apparatus for making foil blanks from an elongated band on a roll and for applying said blanks to objects, said apparatus comprising: a pair of upstream rollers gripping said band; drive means connected to said upstream rollers for rotating same at a constant peripheral speed and thereby pulling said band off said roll at said speed and advancing said band downstream along a band path; means including a glue-applying roller downstream of said upstream rollers for applying adhesive to one face of said band in spots spaced apart on said one face transverse to the travel direction of said band along said band path; a pair of downstream rollers gripping said band downstream of said glue-applying roller, one of said downstream rollers engaging said one face only between said spots; means including a deflector engageable with said band between said glue-applying roller and said downstream rollers on said one face only between said spots for periodically deflecting said band between said upstream and downstream rollers perpendicular to said travel direction and thereby periodically stopping said band at said downstream rollers; means including a slip clutch between said downstream rollers and said drive means for urging said downstream rollers into rotation at a peripheral speed substantially greater than that of said upstream rollers and for permitting said downstream rollers to stop rotating completely when said band stops at said downstream rollers; means including a cutter operable synchronously with said deflector and downstream of said downstream rollers for cutting through said band when same stops at said downstream rollers, and thereby forming a blank; means operating synchronously with said cutter and deflector for conveying said objects through a station on said band path immediately downstream of said downstream rollers along an object path passing transversely through said band path at said station with one object being positioned in said station each time said band stops thereat; means including a holder engageable with the blank in said station and therethrough with the object therein for pressing said blank against said object when said band stops and said cutter cuts through said band; and means along said object path downstream of said station for wrapping said blank tightly around said object as same is transported away from said station.
Claim 3
Dependent Claim
