Abstract
Abstract An improved machine for tying tape around articles so as to bundle them. An openable, hoop-shaped tape guide forms a loop of tape around articles to be tied together. A first clamp holds the leading end of the tape while the machine takes up slack in the tape thereby tightening it around the articles. A second clamp holds the trailing portion of the tape while the remaining tape is severed and the two ends of the tape loop are twisted together by rotation of the clamping mechanism. The improvement comprises a rotatably-mounted cam which produces positive-action sequential actuation of the clamps and a tape-cutting knife by pushing against several cam followers directly connected to push members which respectively operate the clamps and knife. The improvement also provides a simplified mechanism having a push member directly responsive to the aforementioned cam for closing and opening the tape guide at the beginning and end, respectively, of the tying cycle. A series of lobes formed in the surface of the cam displace the push members and fix the time relationship and sequence of the aforementioned events.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
218 words
An improved tying machine having selectively openable and closeable loop-forming means for forming a length of tying tape into a loop around an article to be tied, tape-feeding means for feeding said tape into said loop-forming means whereby a loop of tape is formed around said article, a first clamp means for clamping the leading end of said loop, means for tightening said loop around an article to be tied, a second clamp means for clamping a trailing portion of said tape forming said loop, knife means for severing said loop from the remainder of said tape, and twister means for twisting the ends of said loop together to secure said article, wherein the improvement comprises three push-member assemblies mounted in said machine, each engaging at one end thereof said first clamp means, said second clamp means and said knife means respectively, for independently actuating said respective clamp and knife means, and a cam means rotatably mounted in said machine adjacent the opposite ends of said respective push-member assemblies for actuating said clamp means and knife means, said cam means having three respective lobes distributed axially and peripherally over its exterior surface for sequentially displacing each of said push-member assemblies solely by the direct application of compressive force thereto in response to the rotation of said cam means.
Claim 2
Dependent Claim
218 words
An improved tying machine having selectively openable and closeable loop-forming means for forming a length of tying tape into a loop around an article to be tied, tape-feeding means for feeding said tape into said loop-forming means whereby a loop of tape is formed around said article, a first clamp means for clamping the leading end of said loop, means for tightening said loop around an article to be tied, a second clamp means for clamping a trailing portion of said tape forming said loop, knife means for severing said loop from the remainder of said tape, and twister means for twisting the ends of said loop together to secure said article, wherein the improvement comprises three push-member assemblies mounted in said machine, each engaging at one end thereof said first clamp means, said second clamp means and said knife means respectively, for independently actuating said respective clamp and knife means, and a cam means rotatably mounted in said machine adjacent the opposite ends of said respective push-member assemblies for actuating said clamp means and knife means, said cam means having three respective lobes distributed axially and peripherally over its exterior surface for sequentially displacing each of said push-member assemblies solely by the direct application of compressive force thereto in response to the rotation of said cam means.
Claim 3
Dependent Claim
86 words
The improved tying machine of claim 1 wherein the push-member assembly for actuating said first clamp means includes a surrounding portion disposed about the push-member assembly for actuating said second clamp means, and wherein the lobe on the surface of said cam means which displaces said first push-member assembly is split into two parts which are located on either side of the lobe which displaces said second push-member assembly, said split lobe actuating said first clamp means by pushing against said surrounding portion at two points.
Claim 4
Dependent Claim
62 words
The tying machine of claim 1, further including a fourth push-member assembly pivotally connected at one end to said loop-forming means for operating the same, and a rotatably-mounted cam at the other end of said fourth push-member assembly for sequentially displacing said fourth push-member assembly, said cam being synchronized with said cam means which actuates said clamp means and knife means respectively.
Claim 5
Dependent Claim
31 words
The tying machine of claim 3 wherein said cam which displaces said fourth push-member assembly is an integral part of said cam which actuates said clamp means and knife means respectively.
Claim 6
Dependent Claim
172 words
An improved tying machine having selectively openable and closeable loop-forming means for forming a length of tying tape into a loop around an article to be tied, tapefeeding means for feeding said tape into said loop-forming means whereby a loop of tape is formed around said article, a first clamp means for clamping the leading end of said loop, means for tightening said loop around an article to be tied, a second clamp means for clamping a trailing portion of said tape forming said loop, knife means for severing said loop from the remainder of said tape, and twister means for twisting the ends of said loop together to secure said article, wherein the improvement comprises a push-member assembly mounted in said machine and pivotally connected at one end to said loop-forming means for operating the same, and a rotatably-mounted cam at the other end of said push-member assembly synchronized with the actuation of said clamp means and said knife means for sequentially displacIng said push-member assembly for opening said loop-forming means.
Claim 7
Dependent Claim
172 words
An improved tying machine having selectively openable and closeable loop-forming means for forming a length of tying tape into a loop around an article to be tied, tapefeeding means for feeding said tape into said loop-forming means whereby a loop of tape is formed around said article, a first clamp means for clamping the leading end of said loop, means for tightening said loop around an article to be tied, a second clamp means for clamping a trailing portion of said tape forming said loop, knife means for severing said loop from the remainder of said tape, and twister means for twisting the ends of said loop together to secure said article, wherein the improvement comprises a push-member assembly mounted in said machine and pivotally connected at one end to said loop-forming means for operating the same, and a rotatably-mounted cam at the other end of said push-member assembly synchronized with the actuation of said clamp means and said knife means for sequentially displacIng said push-member assembly for opening said loop-forming means.
