Abstract
Abstract A method and apparatus for inserting packets of articles into a container characterized by positioning a strip of thin material in front of at least one of the packets, gripping a marginal edge of the material so that the insertion of the packet causes bending of the material adjacent the marginal edge and draws the remaining portion of the material into the box to be disposed along the side of the packet. Preferably, the method and apparatus is utilized for interleaving a strip of thin material between a pair of packets disposed in a container. The device utilizes a table having a strip guideway adjacent one edge formed by the gripping device and a tong device which is carried by a moveable stop along the strip guideway. The strip of thin material is preferably provided from a roll and the apparatus includes the cutting device which severs the portion of the strip, which was drawn into the guideway by the tongs, from the remaining portion.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
92 words
A method of inserting a strip of thin material along a side of a packet of articles which packet is inserted into a container having an opening, said method comprising the steps of positioning a strip of the thin material adjacent to the opening of the container, gripping a marginal edge of the strip, inserting a packet into the container, said packet bending the strip adjacent to the marginal edge being gripped and carrying the remaining portion of the strip into the container to be disposed along the side of the packet.
Claim 2
Independent Claim
92 words
A method of inserting a strip of thin material along a side of a packet of articles which packet is inserted into a container having an opening, said method comprising the steps of positioning a strip of the thin material adjacent to the opening of the container, gripping a marginal edge of the strip, inserting a packet into the container, said packet bending the strip adjacent to the marginal edge being gripped and carrying the remaining portion of the strip into the container to be disposed along the side of the packet.
Claim 3
Dependent Claim
77 words
A method according to claim 1, wherein the step of positioning includes unreeling the strip from the roll of thin material by drawing the strip across the opening of the container by gripping the sheet adjacent said one marginal edge and moving the strip in a direction parallel to said edge, said method including the step of cutting the portion of the strip to the desired length after positioning the strip at the opening of the container.
Claim 4
Dependent Claim
42 words
A method according to claim 2, wherein the steps of unwinding the strip is accomplished simultaneously with a step of feeding the articles to form the packet so that the length of the strip is dependent on the size of the packet.
Claim 5
Dependent Claim
47 words
A method according to claim 1, which includes inserting a first packet into the container prior to positioning the strip so that the strip carried into the container by the insertion of a following packet after positioning is disposed between a pair of packets in the container.
Claim 6
Independent Claim
147 words
An apparatus for inserting a packet of articles into a container having an opening with a strip of thin material disposed along one side of the packet, said apparatus comprising a surface for supporting a packet of articles, means supporting a container adjacent an edge of said surface, means for inserting a packet disposed on said surface into the container, means disposed at an edge of the surface adjacent the support means of the container for gripping a marginal edge of a strip of thin material to position the material in the path of the packet being inserted into the container so that as the packet is inserted into the container by the inserting means, the packet will fold the thin material adjacent said marginal edge and draw the remaining portion of the thin material into the container to be disposed along a side of the packet.
Claim 7
Independent Claim
147 words
An apparatus for inserting a packet of articles into a container having an opening with a strip of thin material disposed along one side of the packet, said apparatus comprising a surface for supporting a packet of articles, means supporting a container adjacent an edge of said surface, means for inserting a packet disposed on said surface into the container, means disposed at an edge of the surface adjacent the support means of the container for gripping a marginal edge of a strip of thin material to position the material in the path of the packet being inserted into the container so that as the packet is inserted into the container by the inserting means, the packet will fold the thin material adjacent said marginal edge and draw the remaining portion of the thin material into the container to be disposed along a side of the packet.
Claim 8
Dependent Claim
64 words
An apparatus according to claim 5, wherein the means for gripping the marginal edge comprises an elongated part coacting with said edge of said surface, said elongated part being moveable relative to said edge from a first position for gripping material to a second position withdrawn from said edge to form a guideway for the movement of the marginal edge of the material therebetween.
Claim 9
Dependent Claim
57 words
An apparatus according to claim 5, which includes tong means for grasping the strip adjacent the marginal edge, said tong means being moveable across said surface from a first to a second position for drawing a strip of said thin material along said edge of said surface into position prior to being gripped by said gripping means.
Claim 10
Dependent Claim
62 words
An apparatus according to claim 7, which further includes means for storing a roll of the strip material adjacent one end of the gripping means and cutting means disposed adjacent said one position of the tong means for severing the portion of the strip of material drawn by the tong means from the roll into the gripping means to the desired length.
Claim 11
Dependent Claim
61 words
An apparatus according to claim 8, which further includes a moveable stop disposed on said surface, said stop being moved by the forming of a packet on the surface, said tong means being connected to said moveable stop to move therewith so that the tong means draw the strip of material into position as the packet is formed on said surface.
Claim 12
Dependent Claim
96 words
An apparatus according to claim 9, wherein said tong means includes a follower disposed beneath said surface, a cam slideably mounted beneath said surface adjacent the cutting means and attached to means for moving the cam into and out of the path of the follower to selectively cause the follower to open said tong means and a second cam disposed beneath said surface in the path of the follower at the second position of travel of the tong means, said follower engaging the cam to cause the tong means to open when reaching the second position.
Claim 13
Dependent Claim
19 words
An apparatus according to claim 10, wherein the cutting means comprises a cutting wheel moveable vertically in a groove.
