IMPRINTING METHOD

An imprinting method, which includes following steps. A workpiece is conveyed to a working region by a first conveyer unit. The workpiece is imprinted in the working region through an imprinting segment of a flexible imprinting mold film. The flexible imprinting mold film is driven by a driving roller set, such that at least another one of the imprinting segments of the flexible imprinting mold film rolled around the driving roller set is expanded from the driving roller set and moved to the working region.

Method and apparatus for applying annular doses

A method and an apparatus for forming annular doses provides a flow of plasticised material supplied by an extruder which passes through a channel that is first cylindrical and then annular. The material exits from an annular outlet in front of which a cutting element passes that separates an annular dose of material. The dose is deposited on a surface of a capsule having a capacity to adhere to the dose that is greater than the cutting element. The surface and the cutting element are distanced from one another in such a manner that the annular dose remaining adhering to the capsule is detached from the element. Detachment can be promoted by a flow of air.

Methods and apparatus for positioning a structure on a polymer layer

Methods and apparatus for positioning a structure on a polymer layer are described. A method may involve forming a first polymer layer. The method may further involve positioning, by an apparatus, a structure on the first polymer layer, where the apparatus comprises a rod having a first end that supports the structure as the structure is being positioned and a plunger located around the first end of the rod that presses the structure onto the first polymer layer as the structure is being positioned. And the method may involve forming a second polymer layer over the first polymer layer and the structure, where the first polymer layer defines a first side of a body-mountable device and the second polymer layer defines a second side of the body-mountable device opposite the first side.

Method of warming a mold apparatus

A method of releasing ice from a mold apparatus is disclosed which includes the steps of: providing a mold apparatus having a first mold portion including a concave depression and a liquid circulating manifold and a second mold portion having a concave depression; pivotally coupling to the first mold portion to the second mold portion such that the mold apparatus is operable between an ice forming position and an ice harvesting position; assembling the mold apparatus to the ice forming position such that the concave depressions abut to from a mold cavity; injecting water into the mold cavity; cooling the mold apparatus; forming at least one ice structure within the mold cavity; circulating a warm liquid medium in the liquid circulating manifold to warm the mold apparatus; disassembling the mold apparatus to the ice harvesting position; and releasing the at least one ice structure from the mold apparatus.

Injection mold

An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.

Apparatus and method for stretching and taking-away polymer films

A film (50) processing apparatus (20) including a film stretching device (22) and a take-away device (24) and a film processing method using the apparatus. The take-away device receives the film after the stretching device and transports the film along a conveying region in a direction of transport (X). The take-away device includes opposing, first and second conveyor assemblies. The first conveyor assembly has a continuous belt driving a plurality of discrete pads (180a, 180b). Each pad forms a contact face (194a, 194b) extending between leading (200b) and trailing edges (202a). The pads are configured and arranged such that the trailing edge (202a) of a first pad (180a) overlaps the leading edge (200b) of an immediately adjacent second pad (180b) as the first and second pads traverse the conveying region. The overlap is characterized by a line (322) perpendicular to the direction of transport passing at any given moment through the first and second pads. A shape of the contact face can define a major central axis that is non-perpendicular and non-parallel with the direction of transport.

Method for controlling a materials handling installation with securing of means of access for maintenance

Disclosed is a method for controlling an installation for handling hollow bodies, which includes: a plurality of treatment units; a transfer system; and a covering including a frame that defines casings and door leaves each mounted on a casing; a control unit. Also included are steps of: detection by the control unit of the stopping of a treatment unit; detection by the control unit of the closed position of door leaves located in the vicinity of an interface between the detected treatment unit that is stopped and the transfer system; and if these door leaves are detected in closed position, ordering by the control unit of the locking of these door leaves.

Systems and methods of feeding hook fastening elements

Systems and methods for introducing hook fastening elements into a mold traveling along a mold assembly line are disclosed. The system can be configured to cut hook fastening tape into strips having a predetermined length based on information received from the mold assembly line, and to drop the cut strips directly into the mold at the appropriate intervals as the mold travels along the mold assembly line. Also disclosed is a system for facilitating the continuous feeding of hook fastening tape through the system.

EXTRUSION PRESS SYSTEMS AND METHODS
20200047232 · 2020-02-13 ·

Systems, devices, and methods are described for extruding materials. In certain embodiments, one or more hollow billets are loaded onto an elongate mandrel bar and transported along the mandrel bar to a rotating die. The billets are transported through fluid clamps, which engage the mandrel bar and provide cooling fluid to the mandrel bar tip, and through mandrel grips, which engage the mandrel bar and prevent the mandrel bar from rotating. One or more press-rams advance the billets through a centering insert and into the rotating die. A quench assembly is provided at an extrusion end of the extrusion press to quench the extruded material. A programmable logic controller may be provided to control, at least in part, operations of the extrusion press system.
