摘要:
A manufacturing apparatus and a manufacturing method that can form in successive processes tooth-marks longitudinally at a regular pitch on the back side of a passenger-conveyor moving handrail. The manufacturing apparatus includes: a material feed port through which a thermoplastic resin is fed; a heater that heats the fed thermoplastic resin; a molding machine that extrusion-molds the thermoplastic resin having been fluidized; and a tooth-mark forming tool, which is a tooth-mark forming device, that forms tooth-marks longitudinally at a regular pitch on the back side of a preformed moving-handrail material having been extrusion-molded, while it is in a state in a plastically deformable temperature range.
摘要:
A mold for a machine which is used for the blow molding of containers from performs. The inventive mold includes a wall defining a cavity that is intended to receive a preform. In addition, the mold includes at least one mold insert which is equipped with a lug and which is mounted such that it can move in relation to the wall by means of a cam system, between: an out position in which the lug projects out at least partially from the wall into the cavity, and a retracted position in which the lug is retracted into the wall. The invention also relates to a method of producing a container by means of blow molding using one such mold.
摘要:
A method of manufacturing a mirror assembly (14) by placing a beveled mirror (18) within a carrier (19) prior to inserting the carrier into a mirror handle head (23). The mirror handle head (23) is inserted into a mold position (27) and a molten thermoplastic resin is introduced into the mold. A series of mirror retaining clips (20) formed integrally with the carrier (19) maintain the mirror (18) in a precise location during the molding process and permit resin to overlay the mirror bevel (35) without reaching the mirror surface (22). The mirror handle (15) may be customized during manufacture to include a ribbed, soft grip region (16, 17) by forming a handle core (36) that includes a recessed region defined by shoulders (43, 44). A central region of the core (36) includes voids that define characters or symbols (38, 39, 40, and 41) that are filled with a thermoplastic material during a molding process (4). Alternatively, the handle (15) may be formed during a single molding process and attached to the handle head (23) during formation of the mirror retention lip (49).
摘要:
A substantially rigid, fiber reinforced polymer composite article that includes a preprinted veil layer covered with a substantially transparent capstock that is designed to be used for implement handles, such as shovels and rakes or can be used for decking and fencing material. The fiber reinforced polymer composite article is formed of by using pre-impregnated fiberglass rovings or fibers encapsulated in a thermoplastic capstock that are pultruded through one or more dies and coated with a veil material. The veil material includes a pattern that, when applied to the fibrous layer can create the appearance of wood or simulate other materials. The veil layer is then coated with a transparent or substantially transparent capstock by means of extrusion to produce the fiber reinforced polymer composite article.
摘要:
A plastic container having a body portion and a handle portion which extends from the body portion is formed using a pair of mold halves placed into engagement. During the molding process, a surface of the handle portion is provided with a recess in at least one area where the mold halves are in placed into engagement.

A method of making a preform assembly includes providing a preform having a closed end, and providing an attachment object having a ring. The attachment object is assembled to the preform by telescoping the ring over the closed end of the preform until the ring is brought into abutting engagement with a portion of the preform in such a way that interference between the ring and the portion of the preform prevents dislodgement or removal of the attachment object during subsequent processing of the preform assembly. The attachment object in the disclosed embodiments of the invention may be a handle, a label or a shroud. The ring on the attachment object may be circumferentially continuous or circumferentially split. Engagement between the attachment object ring and the preform may be by engagement with one or more external protrusions on the surface of the preform, or may be by interference press fit engagement between the ring and the external surface of the preform.
摘要:
A moldable article that can be custom-fitted to a particular user. Such an article comprises a thermoplastic material such as ethylene vinyl acetate modified by an antistatic agent selected from the group consisting of polyol amines such as ethoxylated amines, ethoxylated fatty alcohols, phosphoric acid esters, quaternary ammonium salts, and amphoteric compounds such as betaine. The article is heated until the thermoplastic material softens, then pressed against a user's body part. The article is allowed to cool, resulting in a custom-fitted article. Such articles may be repeatedly re-heated and re-molded and may include, e.g., moldable footbeds, racquet handles, shin guards, helmets, and seats.
摘要:
A hollow plastic article having a wall with an inside wall portion and an outside wall portion, wherein a part of the outside wall portion has a slip resistant, tactile surface relative to the remainder of the outside wall portion to provide an improved gripping surface on the article.

This invention is aimed at providing a biaxially drawn, blow-molded PET bottle with a handle, which bottle is highly safe and easy to handle, even in the case of large-size bottles with a capacity as large as a few liters. This can be achieved by improving the insert moldability of the handle and by increasing the strength of fitting of the handle to the bottle. Such a bottle with a handle comprises a polyethylene terephthalate resin bottle and a handle, an injection-molded product made of a synthetic resin, which is fitted firmly to the bottle as an insert. This bottle has a recession that has been caved in at the rear of body and also comprises a vertical projecting wall disposed in the central part of the bottom of this recession. The handle comprises a pair of fitting beams disposed in parallel to each other in the standing position and a grip plate integrally disposed to connect between the pair of fitting beams at both the upper and lower ends thereof. Embedded ridges are disposed broadly in the direction of central axis of the preform at the positions where said embedded ridges stem from the pair of the fitting beams and extend from the base toward the front end face while expanding in width, so that the front end faces are opposed to the periphery of the preform under the condition that the handle is set inside the blow-molding tool. A part of the fitting beams and embedded ridges constitute the handle inserts that are fitted to the recession bottom on both sides of the vertical projecting wall of the bottle.
摘要:
A method of making a container by providing a container having a neck, providing a container attachment having a circumferentially continuous ring, telescoping the ring over the neck, and radially expanding at least a portion of the neck to secure the attachment to the neck.
