Abstract: A coating method includes a first step for spraying, onto an inner area of an opening part of a cylindrical body having a bottom and arranged horizontally, a first coating material of synthetic resin containing non-volatile components while rotating the cylindrical body around a central axis thereof. After the first step, a second step is performed for spraying, onto an inner area of a barrel part of the cylindrical body, a second coating material of synthetic resin containing a lower proportion of non-volatile components than that of the first coating material while continuing to rotate the cylindrical body. After the second step is performed and before the volatile components of the second coating material vaporizes, a third step is performed in which the rotation of the cylindrical body is stopped, the cylindrical body is placed vertically, and the volatile components of the second coating material are vaporized.

Abstract: A can body maker includes a ram shaft extending in a front-rear direction, a punch disposed at a front end portion of the ram shaft, a reciprocating linear motion mechanism connected to a rear end portion of the ram shaft to reciprocate and linearly move the ram shaft in the front-rear direction, a die having a through hole into which the punch is inserted, a cup holding mechanism which presses a cup-shaped body against an end face in which the through hole of the die opens, and a cup holder drive mechanism that oscillates the cup holding mechanism in the front-rear direction, wherein the cup holder drive mechanism has a cam structure and is disposed directly below the cup holding mechanism.

Abstract: A housing including an internal gear having a first central axis as a center; a first rotating body relatively rotatably joined to the housing ; a second rotating body including an external gear having a second central axis parallel to the first central axis as a center and meshing with an internal gear and relatively rotatably joined to the first rotating body; a ram shaft joining part connected to the second rotating body and configured to be linearly moved in a reciprocating manner in a prescribed direction; and an air supply path passing through the insides of the first rotating body, the second rotating body, and the ram shaft joining part are provided.

Abstract: Provided is a can inner surface-coating apparatus with which inspection of bottomed cylinders can be favorably performed in parallel without being affected by the coating process. In the can inner surface-coating apparatus, inspection cameras to be used for inspection following coating of the inner surface of a bottomed cylinder that will become the body of a can or bottle-shaped can are disposed above spray devices that are used for coating the inner surface of bottomed cylinders. Moreover, the coating area including the spray devices and the inspection area including the inspection cameras are covered with a cover. By supplying air inside the cover from the upper part (air supply port) of the inspection area and discharging the air out of the cover from the lower part (coating mist collection duct) of the coating area, an air flow is formed from the upper part of the inspection area to the lower part of the coating area.

Abstract: Improvements in a stackable construction panel system are disclosed. The system includes stackable wall forms for receiving a flowable material, each form having a pair of foam panels tied together in a spaced and parallel relationship by connectors. In a first improvement, the connectors have head pieces with transversal terminal surfaces facilitating the stacking and handling of the wall forms on construction sites. In a second improvement, an end panel assembly is provided for mounting an end panel used as a wall stud for the construction of a window or door frame. The end panel assembly has first and second engaging members, each removably engageable with side end portions of the pair of foam panels. The end panel itself is mountable therebetween. In accordance with a third improvement, a corner connector is provided for reinforcing corner wall forms.

Abstract: A ledger mould assembly is suitable for use with a wall form assembly of the type comprising a pair of spaced-apart parallel foam panels defining therebetween a cavity for the setting of a flowable material for building an insulated wall. The ledger mould is used to receive a hardening flowable material and integrally forming a ledger to the wall. The ledger mould assembly comprises an elongated mould made of foam having a planar front face spanning from top to bottom, a tapered bottom edge and at least one flared recess in the front face, opening outwardly and upwardly from bottom to top. Mounting means are provided for horizontally mounting the mould against either one of the foam panels with the bottom down and the planar front face of the ledger mould in contact with the planar outside face of the foam panel. This set-up allows flowable hardening material to be poured from the top of the mould into the flared recesses to form a ledger once it has hardened.

Abstract: A connector for tying together opposed foam panels in spaced and parallel relationship to make a form for receiving flowable material is disclosed. The connector comprises a pair of anchor members, one being devised to be embedded in one of the foam panels and the other being devised to be embedded in the other one of the foam panels. Each of these anchor members has a projecting end devised to come out of the foam panel once the anchor member is embedded therein. The connector further comprises a web member extending between the foam panels. The web member has opposite longitudinal side ends, each of the side ends being hingedly connectable to the projecting end of either one of the anchor members. Thanks to such a connector, the tied foam panels of the form wall assembly are movable between an extended position where the foam panels are spaced-apart to make the form and a collapsed position where the foam panels are brought close to each other for transportation purposes.

Abstract: A stackable insulating foam panel which has a top side and a bottom side. Each of the panels has a median row of alternating projections and recesses with a similar complementary shape. The median row is disposed between two coplanar edge surfaces. Each projection of the top side is opposed to a recess of the bottom side whereby the top side and/or the bottom side of the panel can be interconnected with either the top side or the bottom side of a like panel. The present invention also concerns a wall form assembly which comprises opposed foam panels disposed in parallel relationship to make a wall form for receiving a flowable material such as concrete and a plurality of connectors for tying the opposed foam panels together.

Abstract: The packing protector is formed from an elongated strip of flexible cushioning material having an L-shaped cross section defining a vertical wall and a vertical wall. Transversal folding lines are provided in the strip to fold it in the shape of the packing protector. The folding line is formed by a groove spanning transversally on an inner side surface of the vertical wall. The groove is associated with a V-shaped folding cutout in the horizontal wall shaped to form two matching surfaces which are brought adjacent to each other when the strip is folded, thereby forming a unified wall. One of the two matching surfaces includes a male coupling interlockable with a female coupling in the other matching surface to keep the strip once folded in the form of the packing protector. A packing protector according to the present invention has the advantage of being easy and simple to ship to the user or purchaser in great amounts, as the unfolded strips can be easily piled up for the delivery.
