Abstract
Abstract A device for automatically transferring an adhesive film having adhesive on both faces thereof from a roll of adhesive tape to an article. The device has a frame having a pair of support plates and a roll support shaft provided therebetween on which a roll of the adhesive tape is mounted, the tape roll including a rolled adhesive film having pressure sensitive adhesive on both faces thereof and a rolled removable spacer tape disposed between the adjacent turns of the adhesive film. The roll of adhesive tape is so arranged that the lower adhesive face protrudes beyond the lower edge of the frame. A device to feed the removed spacer tape out of the device is provided at the top of the frame. This feeding device can be a pair of pieces having an opening provided therebetween so as to guide the removed spacer tape out of the device after its removal from the adhesive film. The roll of adhesive tape is rollingly forced against an article so that the adhesive film is transferred to the article while the removable spacer tape is separated from the adhesive film and fed out of the device by the feeding out device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
157 words
A tape dispenser and tape package for transferring an adhesive film from a roll of adhesive tape to an article, consisting of a frame having a roll support shaft; a roll of adhesive tape rotatably mounted on said roll support shaft and having a rolled adhesive film having pressure-sensitive adhesive on both faces thereof and a rolled removable spacer tape disposed between the adjacent turns of said adhesive film, said transferring adhesive tape roll when mounted on said roll support shaft having the lowermost portion of the periphery thereof protruding beyond the lower edge of said frame; and means spaced around said frame from said lowermost portion for engaging only the spacer tape and separating it from the next inward turn of adhesive tape and feeding said removable spacer tape out of said frame after it is separated from said adhesive film which has stuck to an article and from the next underlying turn of adhesive tape.
Claim 2
Dependent Claim
157 words
A tape dispenser and tape package for transferring an adhesive film from a roll of adhesive tape to an article, consisting of a frame having a roll support shaft; a roll of adhesive tape rotatably mounted on said roll support shaft and having a rolled adhesive film having pressure-sensitive adhesive on both faces thereof and a rolled removable spacer tape disposed between the adjacent turns of said adhesive film, said transferring adhesive tape roll when mounted on said roll support shaft having the lowermost portion of the periphery thereof protruding beyond the lower edge of said frame; and means spaced around said frame from said lowermost portion for engaging only the spacer tape and separating it from the next inward turn of adhesive tape and feeding said removable spacer tape out of said frame after it is separated from said adhesive film which has stuck to an article and from the next underlying turn of adhesive tape.
Claim 3
Dependent Claim
60 words
A tape dispenser and tape package as claimed in claim 1, wherein said means to feed said removable spacer tape comprises a pair of pieces along the periphery of said frame having an opening therebetween extending parallel to said support shaft and through which said spacer tape is fed out of said frame as said roll of adhesive tape rotates.
Claim 4
Dependent Claim
36 words
A tape dispenser and tape package as claimed in claim 2, wherein at least one of said pair of pieces is mounted on said frame resiliently engaging said adhesive tape roll on said roll support shaft.
Claim 5
Dependent Claim
150 words
A tape dispenser for transferring an adhesive film from a roll of adhesive tape to an article, the roll having a rolled adhesive film with pressure sensitive adhesive on both faces thereof and a rolled removable spacer tape disposed between adjacent turns of said adhesive film, said dispenser consisting of a frame having a roll support shaft, the lower edge of said frame being aligned with the lowermost peripheral portion of said support shaft, and means spaced around said frame from said lowermost peripheral portion of said support shaft and positioned for engaging only the spacer tape and separating it from the next inward turn of adhesive tape and feeding removable spacer tape out of said frame after it has been separated from the adhesive film, whereby the roll of adhesive tape can be mounted on said roll support shaft and will protrude beyond the lowermost edge of said frame.
