Abstract
Abstract Apparatus for providing adhesive strips having a predetermined length includes a rotatable reel for support of a roll of adhesive tape. A conveyor, which may be a rotatable turn table, is provided for supporting thereon a plurality of adhesive strips which have been cut to a predetermined length from the roll of adhesive tape. A feed member is pivotably supported adjacent one end thereof for movement between a first position adjacent the reel and a second position adjacent the conveyor. The feed member carries a stationary cutter plate and a cutter bar which is reciprocable therealong and is cooperable with the cutter plate to cut adhesive tape withdrawn from the reel into strips of the predetermined length. The feed member carries at its outer end a latch plate for selectively grasping and retaining the free end of adhesive tape withdrawn from the reel. A lever rod is carried by the feed member and is movable longitudinally thereof and is operably connected to the latch plate. A series of cams are drivable to sequentially move the feed member, latch plate, cutter bar and conveyor. By the arrangement of the invention predetermined lengths of adhesive tape are serially withdrawn from the reel by pivotal movement of the feed member from the first position to the second position and are positioned on the conveyor, the cutter bar is reciprocated into cooperation with the cutter plate so as to cut the tape into the strips upon return of the feed member to the first pivotal position.

Apparatus for providing adhesive strips of predetermined length comprising in combination: a rotatably mounted support member for a roll of adhesive tape; means for supporting a plurality of adhesive strips which have been cut to a predetermined length; a feed member pivotably supported for pivotal movement between a first position adjacent said adhesive tape support member and a second position adjacent said adhesive strip support means, said feed member being provided with a cutter plate and a cutter bar movable longitudinally thereof and cooperable with said cutter plate to cut the adhesive tape into strips of predetermined length; means carried by said feed member for retaining the free end of the adhesive tape of said roll; a lever rod carried by said feed member movable longitudinally thereof and operably connected to said tape retaining means; and a plurality of cam means drivable to sequentially move said feed member, tape retaining means, cutter bar and adhesive strip support means; whereby predetermined lengths of adhesive tape are serially withdrawn from said tape support member by pivotal movement of said feed member from said first position to said second position and positioned on said adhesive strip support means, and cut into strips of predetermined length of said cutter bar in cooperation with said cutter plate upon return of said feed member to said first position.
Claim 3
Dependent Claim
99 words
Apparatus according to claim 1, wherein said feed member is provided with a slide bar movable longitudinally thereof, said tape retaining means being a latch plate pivotably mounted at an end of said slide bar, and said lever rod being pivotably connected at one end thereof with said latch plate, said feed member having an opening dimensioned to permit the passage of the adhesive tape therethrough and said latch plate being pivotable to selectively grasp and retain the free end of the adhesive tape in one pivotal position thereof and to release such tape in another pivotal position thereof.
Claim 4
Dependent Claim
83 words
Apparatus according to claim 1, wherein said feed member is mounted pivotably on a shaft and said cam means includes a first cam operable to engage with one end of said lever rod to cyclically reciprocate said lever rod relative to said feed member and a second cam operable to engage with one end of said cutter bar to cyclically reciprocate said cutter bar relative to said cutter plate, said first and second cams and said feed member being mounted on said shaft.
Claim 5
Dependent Claim
52 words
Apparatus according to claim 1, wherein said adhesive strip support means comprises a rotatable turntable, and an oscillatable lever is provided and operably connected to said feed member, one of said cam means being engageable with said oscillatable lever for pivoting said feed arm into one of said first and second positions.
Claim 6
Dependent Claim
74 words
Apparatus according to claim 4, including adjustable means for limiting the pivotable movement of said feed member so as to thereby establish said first position, said one cam means having a contour so as to control the pivotal movement of said oscillating lever and thereby to establish said second pivotal position for said feed member, the extent of pivotal movement of said feed member thereby determining the length of adhesive strips to be provided.
Claim 7
Dependent Claim
