Patent number: 4950218Abstract: The invention relates to a multiple pot comprising individual pots interconnected by connector portions so as to be capable of being pulled out. The multiple pot is used to raise and transplant seedlings of plants. The invention also relates to a method of fabricating the pot. The pot is designed especially to promote growth of roots across the side walls of the individual pots after transplantation. Also, the resistance encountered when the multiple pot is unfolded is reduced. Further, the individual pots are uniform in size. These feature arise from the facts that the connector portions are formed by applying a waterproof paste discontinuously and that a water-soluble paste is not applied around the edges of the individual pots created when the multiple pot is unfolded. Hence, a coating of the paste is formed in none of these portions. The multiple pot is fabricated by continuously carrying out three steps.Type: GrantFiled: November 7, 1988Date of Patent: August 21, 1990Assignee: Nihon Tensaiseito Kabushiki KaishaInventors: Ryuzo Tsuru, Michinori Sakaki, Masashi Tanimura, Sumio Ito, Hidekazu Terasawa

Patent number: 4578054Abstract: Apparatus for opening flattened cartons having a pair of minor flaps and a pair of major flaps. A constant speed conveyor carries a horizontally disposed flattened carton across an actuator having a cam surface. The cam surface moves upward to fold one pair of major and minor flaps upward and then downward to fold the other pair of major and minor flaps downward. A clamp grasps the upward folded major flap and draws it upward as the conveyor moves the carton forward causing the carton to open. The clamp releases the major flap and the carton moves past a glue gun which applies glue to the minor flaps. A pair of curl bars folds the major flaps against the glue coated minor flaps. An extending platen presses the flaps against a roller bank permitting the glue to set. The platen retracts and the opened and bottom-sealed carton is completed.Type: GrantFiled: November 17, 1983Date of Patent: March 25, 1986Inventor: Robert M. Herrin

Patent number: 4420147Abstract: A machine for folding and gluing a continuous web in high speed operation. A continuous web which has solidified glue thereon in selected regions is folded. Heat is applied to the folded web to melt the glue, particularly in specific areas of the folded web. Pressure is applied to the specific areas to urge together the folded portions of the web and the melted glue therebetween. Then the folded web travels between heat transfer members which rapidly cool the folded web and the glue between folded portions thereof. Thus, the glue is solidified and the folded portions are firmly adhesively attached together.Type: GrantFiled: July 9, 1982Date of Patent: December 13, 1983Assignee: The Standard Register CompanyInventors: William J.

Patent number: 4283190Abstract: A box blank with receptacle and cover sections each with side flaps and end flaps has a hinge panel joining the two sections. A vacuum pickup draws a flat blank from a supply stack to a feed carriage which transfers the blank past sprays that apply glue to the end flaps. The speed of the carrier varies, but beneath the glue sprays speed is uniform. The carriage delivers the glue coated box blank to a former and a tray forming head having concave and convex interacting pressure plates which maintain doubled over end flaps of each section in a concave configuration with respect to the box while the folded end sections are adhered to form a box tray from the blank. Former flap benders cooperate with the tray forming head to shape the box tray. A second vacuum pickup clasps the formed tray at the hinge panel and draws a shaped tray from the forming head into engagement with folding elements such that the cover and receptacle sections are bent together along the hinge panel to form a closed box.Type: GrantFiled: January 30, 1980Date of Patent: August 11, 1981Inventors: Donald F. Williams, Charles L. Phy
