Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
112 words
An apparatus for securing an elastic member to a flexible web of material in a non-linear configuration, said apparatus comprising: (a) a pair of rotatable depositing rolls adapted to deposit said elastic member on a web, said web traveling in a fixed path beneath said depositing rolls; (b) means for rotating said depositing rolls in opposite directions and at the same linear peripheral speed to deposit said elastic member on the surface of said web; (c) means for skewing said depositing rolls with respect to the fixed path to which the web is traveling; said (d) means for moving said depositing rolls transverse of the direction in which said web is traveling.
Claim 2
Independent Claim
112 words
An apparatus for securing an elastic member to a flexible web of material in a non-linear configuration, said apparatus comprising: (a) a pair of rotatable depositing rolls adapted to deposit said elastic member on a web, said web traveling in a fixed path beneath said depositing rolls; (b) means for rotating said depositing rolls in opposite directions and at the same linear peripheral speed to deposit said elastic member on the surface of said web; (c) means for skewing said depositing rolls with respect to the fixed path to which the web is traveling; said (d) means for moving said depositing rolls transverse of the direction in which said web is traveling.
Claim 3
Dependent Claim
36 words
An apparatus in accordance with claim 1 wherein the means for skewing said depositing rolls includes a cam and cam follower for alternately skewing the rolls first in one direction and then in the opposite direction.
Claim 4
Dependent Claim
40 words
Apparatus in accordance with claim 1 wherein the means for moving said depositing rolls in the transverse direction comprises a cam and cam follower for alternately moving said rolls in a first transverse direction and then in the opposite direction.
Claim 5
Dependent Claim
35 words
Apparatus in accordance with claim 3 wherein the means for skewing said depositing rolls includes a cam and cam follower for alternately skewing the rolls first in one direction and then in the opposite direction.
Claim 6
Independent Claim
275 words
An apparatus for securing an elastic member to a flexible web of material in a non-linear configuration, said apparatus comprising: (a) a pair of rotatable depositing rolls adapted to deposit said elastic member to the surface of a web traveling in a fixed path beneath said depositing rolls; (b) a pair of spaced apart vertical shafts; (c) a right angle drive at the bottom of each vertical shaft; (d) a frame member from which the first of said vertical shafts is mounted; (e) a gear train connecting the right angle drive of the first vertical shaft to the depositing rolls; (f) means for driving the right angle drive at the second of said vertical shafts; (g) a pair of timing gears mounted at the top of said vertical shafts; (h) a timing belt connecting said timing gears for imparting drive from the second vertical shaft to the first vertical shaft; (i) a cam mounted at the top of the second vertical shaft; (j) a cam follower cooperating with said cam and being linked to said frame member to skew the frame member and hence the first vertical shaft and the depositing rolls with respect to said flexible web of material; (k) slidably movable frame means from which the second vertical shaft, its right angle drive, and the frame member are mounted; (l) a second cam follower mounted from said frame means; (m) a rotatable cam cooperating with said cam follower; and (n) means for rotating said cam to move the frame means and hence the first vertical shaft and the depositing rolls in a transverse direction with respect to the path of the web material.
