Abstract

Abstract An apparatus for continuously producing containers for the nursing of plant seedlings which are bottomless and square or hexagonal in horizontal cross-section. The apparatus comprises pasting means for continuously applying paste transverse to a tape assembly in the form of lines or dotted lines, means for forming substantially non-pasted units at certain fixed intervals, means for transferring the pasted tape assembly, means for cutting the tape assembly into unit lengths, and rotary laminating means adapted to receive the unit length pieces of tape one by one and laminate them together, all of these means being interlocked with one another to rotate responsive to each other.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 146 words
An apparatus for producing paper cylinder assemblies for the nursing of seedlings or young plants, comprising: feeding means for continuously feeding a stripshaped tape assembly in which a plurality of flattened hollow tapes are overlapped with each other through one half to one third of the width of each tape and bonded together along the overlapped portions; pasting means for applying paste transverse to said tape assembly in the form of lines or dotted lines; cutting means for cutting said tape assembly at a predetermined length to form unit length pieces of said tape assembly; interrupting means for forming unit lengths of substantially non-pasted areas in said tape assembly at predetermined fixed intervals; and rotary laminating means for receiving said unit length pieces one by one and laminating them together, wherein all of said means are interlocked with one another to rotate responsive to each other.
Claim 2
Independent Claim 146 words
An apparatus for producing paper cylinder assemblies for the nursing of seedlings or young plants, comprising: feeding means for continuously feeding a stripshaped tape assembly in which a plurality of flattened hollow tapes are overlapped with each other through one half to one third of the width of each tape and bonded together along the overlapped portions; pasting means for applying paste transverse to said tape assembly in the form of lines or dotted lines; cutting means for cutting said tape assembly at a predetermined length to form unit length pieces of said tape assembly; interrupting means for forming unit lengths of substantially non-pasted areas in said tape assembly at predetermined fixed intervals; and rotary laminating means for receiving said unit length pieces one by one and laminating them together, wherein all of said means are interlocked with one another to rotate responsive to each other.
Claim 3
Dependent Claim 14 words
The device of claim 1 wherein said pasting means comprises a cageshaped pasting roller.
Claim 4
Dependent Claim 83 words
The device of claim 1 wherein said interrupting means comprises a set of cam and gear means associated with said pasting roller and another set of cam and gear means meshed thereto; each of said cam means comprising a protuberance whereby when said cam means are rotated at different rotational velocities, said protuberances will contact one another, thereby, raising up said pasting roller from the surface of the tape assembly upon every predetermined amount of rotation of said meshed cam and gear means.
Claim 5
Dependent Claim 41 words
The device of claim 1 wherein said interrupting means comprises a paper slip applying device; said paper slip applying device including means whereby a unit length of non-pasted paper is transferred and bonded to continuously pasted tape assemblies at predetermined intervals.
Claim 6
Dependent Claim 38 words
The device of claim 1 wherein said feeding means comprises a rose-shaped feed roller having recessed and protruding portions in its surface whereby said tape assembly is fed by stepping over the pasted parts with said recessed portions.
Claim 7
Dependent Claim 67 words
The device of claim 1 wherein said rotary laminating means comprises a rotatable serrated pressure wheel; said serrated pressure wheel including a plurality of sawtooth-like teeth whereby unit length paper cylinders are received by the inside of said teeth and delivered onto a support block while the outside of said teeth push the non-pasted side of the previously delivered unit to paste it to the other units.
