International Classification:

B62D 2500

US Classification:

2961469

Abstract:

A weatherstrip seal comprises a carrier structure without embedded reinforcement that has an attached weather-sealing structure extending therefrom. The carrier structure has two spaced-apart legs connected by a base, the interior walls of the legs forming a channel therebetween. Finger-like members extending from the walls are adapted to frictionally engage and hold a mounting flange inserted into the channel. The legs decrease in thickness as they proceed outwardly from the base and their walls converge inwardly toward each other, minimizing the material required for fabrication of the carrier and enhancing its ability to withstand forces acting to dislodge the mounting flange from the channel, especially at corners thereof.

International Classification:

B29C 4706

US Classification:

264 402

Abstract:

A method of producing a multicomponent extrudate in which the operating line automatically and accurately extrudes the extrudate materials necessary to obtain the desired contribution of materials and specified dimensions of the multicomponent extrudate profile. The screw speed of each extruder can be adjusted to the desired speed by determining the actual thickness and width dimensions of the multicomponent extrudate. The actual measurements are then fed to a computer which calculates the corresponding values of the ratios of the extruder screw speeds to line speed. using the specified dimensions desired in the extrudate, the corresponding values for the screw and line speeds are also calculated. A comparison of the speeds based on measured dimensions, with the speeds based on specified dimensions, provides a measurement by which the screw speeds may then be adjusted such that the measurements of the extrudate profile are brought closer to the specified dimensions of the multicomponent extrudate profile.

Assignee:

GenCorp Inc. - Fairlawn OH

International Classification:

B29C 4724
B29C 4722

US Classification:

4251311

Abstract:

A die assembly for configuring extrudate flow is provided. The die assembly includes a die head having a feed member passage, first and second die head passages, and first and second die surfaces respectively associated with the first and second die head passages. The die head passages are located intermediate the corresponding die surfaces and the feed member passage. A feed member is supported in the feed member passage of the die head and has a feed passage and a feed opening for supplying extrudate to the die head. The feed member is supported for relative movement within the die head whereby the feed opening may be moved to communicate with either the first die head passage or the second die head passage. The central axis feed of the feed opening is moveable with respect to the central axis of the first or second die head passage to correspondingly configure extrudate exiting the respective die head passage when the feed opening is in communication with this die head passage. The die assembly may also include a switch member whereby the die assembly may be supplied with extrudate material from either a first or second extruder.

International Classification:

F16B 100

US Classification:

267293

Abstract:

A slipper bushing assembly including a series of concentric members for permitting controlled sliding movement between a support element and a movable element. The concentric members of the slipper bushing assembly include a rigid one piece inner metal member joined to the support element, a hollow cylindrical elastomeric member, a rigid, one piece hollow outer metal member, a solid slip surface and structure for preventing the inner metal member from disengaging from the outer metal member. The inner metal member has a pair of opposing ends and an outer cylindrical-like surface. The elastomeric member encircles the outer surface of the inner metal member and has a pair of opposing ends, an outer surface and an inner surface. The outer metal member is joined to the movable element and has a pair of opposing ends and an outer cylindrical surface. The slip surface is contiguous to the inner or outer surface of the elastomeric member and coextensive therewith.

Inventors:

James F. Stevenson - Hudson OH

Assignee:

The General Tire & Rubber Company - Akron OH

International Classification:

B29F 302

US Classification:

264 401

Abstract:

A method of producing an extrudate using a roller die is disclosed in which on-line adjustments are made to size and shape deviations by changing the rotational speed of the extruder screw, the feed rate to the extruder, or the speed of the take-away device and the rotational speed of the roller die. The size and shape dimensions of the extrudate are measured and used to calculate new values for the screw or take-away speed of the feed rate and the roller die speed. A measurement of the extrudate dimensions may also be obtained at the roller die to provide a faster response.

Inventors:

William H. Miller - Wadsworth OH
James F. Stevenson - Hudson OH

Assignee:

GenCorp Inc. - Fairlawn OH

International Classification:

B29C 4724

US Classification:

26417716

Abstract:

An assembly and method for processing extrudate material containing curves or angles into a predetermined overall configuration, including having a die assembly for an extruder which assembly controls the cross-sectional shape or profile of the extrudate and selectively varies the path of the extrudate as it leaves the die assembly. A support member is provided which has a predetermined overall configuration and profile to receive the extrudate and maintain its configuration. A driving apparatus is also provided for continuously driving either the support member or the die assembly relative to the other while the extrudate is being received in the support member, and until the entire predetermined overall configuration has been completed. The path of the extrudate is variably directed by the die assembly as it leaves the extruder in coordination with the relative speeds involved to conform the extrudate configuration to the predetermined overall configuration of the support member.

International Classification:

B29C 4792
B29C 4978

US Classification:

425135

Abstract:

A rotatable accumulator roll which may move substantially horizontally or vertically is disposed between the die of an extruder and a take-away conveyor to minimize the effects of output surging of the extrudate from the die of the extruder in order to maintain substantially the dimension of the extrudate as delivered to a constant speed take-away conveyor. Variable force is applied to the roll to maintain tension on the extrudate.
