摘要:
A continuous motion de-flash machine for removing flash from molded plastic articles. An in-feed section is supported by a frame and adapted to transport articles. A de-flash section is supported by the frame, receives articles from the in-feed section, and includes (a) a de-flash turret with a plurality of cam-actuated punch stations each having a punch adapted to remove flash from an article, the punch stations traveling along an oval track with a pair of long straight portions connecting two curved portions, and (b) a nest turret with a plurality of cam-actuated nest stations, the nest stations traveling along an oval track parallel to the oval track of the punch stations. An out-feed section receives an article from the de-flash section and removes the article from the machine. A method of using the machine to de-flash articles having unwanted flash is also disclosed.
摘要:
Extrusion blow mold assemblies, extrusion blow molded articles exhibiting increased strength and enhanced processability, and processes for making said articles. In some aspects, the articles produced herein can include relatively rigid bottles and other containers that exhibit high drop impact performance, while still being relatively easy to deflash. Such containers can be efficiently produced on a commercial scale and are widely usable in a variety of applications, including those in the food, beverage, cosmetic, and medical industries.

摘要:
An apparatus for conditioning plastic containers for putting them into use, in particular ampoules (13), formed into container blocks (11) side by side next to separating lines (17) at which the containers (13) can be separated from one another for use. A pre-separating station (13) is provided, into which the container blocks (11) can be moved in conveying steps and in which a swinging blade (27) is provided for each of the separating lines (17). The swinging blades (27) are coupled to a common drive (31, 33) for a cutting stroke to produce pre-separating incisions at the separating lines (17) such the cutting strokes of each swinging blade (27) takes place in a sequence offset in time in relation to the cutting strokes of other cutting blades (27).
摘要:
A machine (10) for blow molding containers (100). The machine (10) has a stationary flow head (26) located proximate a turntable (12) on which molds (16) are mounted. A dwell cam mechanism (110, 120, 132) on the turntable causes the molds to accelerate ahead of the turntable, stop under the flow head to receive a parison (31), then accelerate to catch up with the turntable. This sequence allows the turntable to rotate continuously. Blow pins (30) mounted on the turntable inject gas into the molds to blow mold the parison while traveling a first path (144). Paddles (142) grip the molded containers and travel a second path (146) radially outward from the first path. The containers blow-molded from the parisons at a first station (18) are retained on the turntable after the turntable completes one full revolution and again passes the first station.
