In the present technology, when rolling rubber material extruded from a first rubber extruder (32) with a first pair of rollers (36, 36) to form a first sheet-shaped member (S1) and layering and rolling the first sheet-shaped member (S1) and the second sheet-shaped member (S2) supplied from an original material with a second pair of rollers (38, 38) to contiguously produce a laminate having the first sheet-shaped member (S1) and a second sheet-shaped member (S2) laminated therein, the gap between the first pair of rollers (36, 36) is controlled on the basis of the detection result of the thickness (d1) of the first sheet-shaped member (S1) rolled by the first pair of rollers (36, 36), the detection result of the thickness (d2) of the second sheet-shaped member (S2) supplied from the original material, and the detection result of the thickness (d3) of the laminate body.

A surface fastener molding apparatus includes a supporting structure and a second supporting structure for axially supporting a mold roll in a rotatable manner at a first end side and a second end side of the mold roll which is opposite to the first end side. The mold roll includes a circumferential surface in which a plurality of mold cavities for molding engaging elements of the surface fastener is provided. A first linear driving means and second linear driving means are provided which are for, respectively, advancing or retracting the first supporting structure and the second supporting structure. The degree of closeness between the extruding nozzle and the mold roll is regulatable across the first end side and the second end side of the mold roll, based on at least one activation of the first driving means and the second driving means.

An injection compression molding system includes a mold having a fixed first half and a displaceable second half. The second half is initially positioned with a cavity between the mold halves having a first clearance sized to receive a molten material puddle shot injected by an injection molding device without the puddle shot filling the cavity. A displacement device acts during or immediately after puddle shot injection, displacing the second mold half toward the first mold half creating a second clearance less than the first clearance. The second clearance defines a finished part thickness whereby displacement of the second mold half to the second clearance compresses the puddle shot so that the puddle shot fills the cavity and forms a finished part between the mold halves. Total time to inject and compress the puddle shot is less than or equal to 1.0 seconds.
摘要:
A calender stack including at least two rollers between which a nip can be formed. The ends of the rollers are supported in rotary fashion in bearings and one of the rollers is stationary and at least one other roller is embodied as an advancing roller and has a first adjusting system by which it is possible to move the bearings of the advancing roller, thus changing the nip. The advancing roller has a respective adjusting system on each of its two bearings and associated with each first adjusting system, a second adjusting system is provided, by which it is possible to adjust an axial offset of the advancing roller relative to the stationary roller.

A container obtained by compression-forming a thermoplastic resin includes a flange portion, a body portion and a bottom portion. A ratio (L/D) of the height of the container to the diameter of the opening is not less than 1.0, and if the direction of height of a test piece cut out from the body portion of the container is denoted by x and the circumferential direction thereof by y, a half-value width P at a half peak of a Miller index at a diffraction angle 2θ=14.5° that represents the diffraction by the crystal plane (110), is in a range of 1.25 to 1.5 over the whole body portion in a peak intensity profile in the direction of height (x-direction) of a Debye's ring obtained by measuring the diffraction intensities by causing the X-rays to be incident on an x-y plane of the test piece at right angles thereto.
摘要:
Edge field patterning of a substrate having full fields and partial fields may include patterning using a template having multiple mesas with each mesa corresponding to a field on the substrate. Polymerizable material may be deposited solely between the template and the full fields of the substrate. A non-reactive material may be deposited between the template and partial fields of the substrate.
摘要:
An apparatus for continuously forming an extruded sheet product having an extruder assembly with a sheet die for delivering flowable material. A roll stand assembly has a main frame with first and second rolls. A vertical height positioning mechanism is operated to vary the relationship between the sheet die and nip location between rolls and has first and second lift components that cooperate with the main frame at first and second laterally spaced locations. The first and second lift components are each movable in first and second opposite paths to selectively elevate and lower the nip location relative to the sheet die. The vertical height positioning mechanism further has an actuating system to selectively and simultaneously cause the first and second lift components to move.
摘要:
A transfer apparatus, for molding a resin on a substrate using a mold on which a pattern is formed and releasing the mold from the resin to transfer the pattern onto the substrate, includes a charge removing device configured to remove a charge of the mold, and a detector configured to detect an electric potential of the mold. The charge removing device is configured to remove the charge of the mold if the electric potential of the mold detected by the detector is not less than a predetermined value.
