摘要： The present invention relates to a novel helical drum shear which is operable to cut a strip of material which moving at a first velocity. The cut is formed along a substantially straight line at a specific angle. The specific angle may be at an angle perpendicular to the feed direction thereby producing a squared cut. The helical drum shear comprises a means for cutting the material wherein the cutting means moves at a second velocity which is at a predetermined angle from the first velocity. The apparatus further comprises a means for moving the cutting means at a third velocity such that the combination of the second velocity and the third velocity is equivalent to the first velocity and the material is helically sheared along a substantially straight line oblique to the first velocity.

摘要： A molded anvil blanket is formed with a projection depending at each end, the ends for abutting when wrapped about the anvil, the anvil having a transverse channel for receiving the projections. The projections mate to form a common recess enclosed by a metal angle member secured to each projection. The angle member and projections have a transverse slot for mounting the blanket end and projections on a pneumatic mechanism attached to the anvil. The mechanism includes an air cylinder secured to the anvil in a radial anvil bore. The cylinder has a shaft which extends in response to pressurized air. A spring attached to the air cylinder and to a T-bar which releasably engages the blanket common recess normally biases the projections locked into the channel in a fail safe mode. The activated air cylinder lifts the projections out of the channel so the blanket ends can be manually released from the anvil by sliding the T-bar out of engagement with the projections via the slots in the projections and angle member.
摘要翻译：模制的砧座毯形成有一个突出部分，每个端部都有一个突出部分，当用砧座缠绕时，用于邻接的端部，砧座具有用于接收突出部的横向通道。突起配合以形成由固定到每个突起的金属角构件包围的公共凹部。角部件和突起具有用于将橡皮布端部和突起部安装在连接到砧座上的气动机构上的横向狭槽。该机构包括在径向砧孔中固定到砧座上的气缸。气缸具有响应于加压空气而延伸的轴。附接到气缸和可释放地接合橡皮布共同凹部的T形杆的弹簧通常在故障安全模式下偏压锁定在通道中的突起。激活的气缸将突出部提升出通道，使得可以通过使T形杆通过突出部和角部件中的槽滑动T形突起而与砧座脱离接合，从而可以从砧座手动释放橡皮布端部。

摘要： A chopper for chopping fibers or fiber strands having a back up roll and a blade roll containing blades that work against a peripheral surface of the back up roll and a method of using is disclosed. The chopper has a number of improved features for reducing the frequency of long fibers or long fiber strands and fuzz from getting into the chopped product. The chopper can have one or any combination of the improvements. The improvements include a strand guide located at least two feet up stream of the chopper, a first starting roll for starting a new strand that runs on a fluid bearing that can be adjusted to control the RPM of the first starting roll, a mount for a roll that runs against the peripheral surface of said back up roll, a strand guide insert for reducing fuzz generation and for preventing fuzz from getting into the product, and a deflector plate for catching and deflecting chopped strands thrown off the back up roll into a chopped strand product chute.
