Claims (1)

[Claims for Utility Model Registration] 1. A device for separating the periphery of an elongated object, comprising: a hollow holding device that holds the elongated object along a central axis against its movement; and a hollow holding device that is rotatable about the central axis with respect to the holding device. a tool head body member, and a tool member pivotally supported by the tool head body member eccentrically with respect to the central axis, and parallel to the pivot axis, and the tool member is pivoted about the central axis in direct response to deceleration of the tool head. a tool head that pivots in a direction; a drive device that rotates the tool head; a brake that decelerates the tool head; a control element configured to actuate a brake in response to the presence of an approaching free end of said elongate object, thereby pivoting the tool member radially toward the elongate object; , an apparatus for peripherally dividing an elongate object, characterized in that it performs a peripherally dividing operation on an elongate object and is further arranged to release a brake when said free end of the elongate object leaves a control element. 2. The brake comprises a brake drum and a device for decelerating the brake drum when the brake is activated, the brake drum being arranged to rotate coaxially with the tool head and having a limited relative relationship between the brake drum and the tool head. Rotation is allowed;
A utility model in which the brake drum is coupled to the tool head such that when the brake is activated, the limited relative rotation causes the brake drum to positively pivot and push the tool member toward the central axis. A device for separating the periphery of an elongated object as claimed in claim 1. 3. When the brake is released while the tool head is rotating at a sufficient speed, the cutting tool element is able to pivot away from the central axis due to centrifugal force, causing the brake drum to move away from said limited relative position. A device for peripherally dividing an elongated object according to claim 2, wherein the brake drum is further arranged to move in a direction opposite to rotation. 4. The tool head includes a cutter arm pivotally connected to the tool head body member adjacent one end of the arm and a cutting tool element adjacent the other end, the cutter arm being radially from the pivot for engagement with the cutting actuation element of the brake drum. Peripheral delimiting device for an elongated object according to claim 2 or 3, which device has a lever element projecting in the direction and is configured to couple the brake drum to the tool member. . 5. Utility Model Registration Claim: The device for separating the periphery of an elongated object according to any one of the preceding claims, wherein the tool member is a cutting tool element for cutting the elongated object in a radial direction. 6 Utility Model Registration Claims Any of the above claims in which the control element is coupled to the drive, the drive is deenergized when the brake is applied, and the control element reenergizes the drive when the brake is released. The device for dividing the periphery of an elongated object according to item 1. 7. The holding device includes a releasable clamp for holding the elongated object against axial movement along the central axis during the peripheral delimitation operation, and the control element clamps and engages the object at the same time as the control element activates the brake. A device for separating the periphery of an elongated object according to any one of the preceding claims, which is configured to release the engagement simultaneously with the release of the brake. 8. A number of locations along the length of the elongated object, the holding device being open at both ends thereof and configured to receive said object that is intermittently fed through the holding device for further passage of the tool member. A device for dividing the periphery of an elongated object according to any one of the preceding claims, which sequentially partitions the periphery of an elongated object. 9. An elongated object is sequentially cut to a predetermined length by making each circumferentially demarcated radial cut by a tool member at a series of locations along the length of the elongated object, said holding device is open at both ends thereof, such that the free end of the elongate object passes through the tool member adjacent to said control element before and during each incision;
A device for peripherally dividing an elongated object according to any one of claims 1 to 7, which is configured to receive an elongated object that is intermittently fed through the holding device. 10. A utility model according to any one of the preceding claims, wherein the holding device includes a cylindrical guide sleeve with a length substantially greater than the inner diameter, and the tool head is attached to one end of the guide sleeve. peripheral separation device for elongated objects. 11. Apparatus for circumferential separation of elongated objects according to claim 10, in which a releasable clamp is attached from the tool head to the other end of the guide sleeve. 12 Utility model registration claim 10 or claim 1, in which the tool head is carried by a guide member and is attached to an outer sleeve that freely rotates coaxially about the guide member, the outer sleeve being part of the drive device. 12. Peripheral separation device for an elongated object according to item 11. 13. The device for dividing the periphery of an elongated object according to any one of the above claims, wherein the control element is an electric limit switch. 14. Utility Model Registration Claim: The device for dividing the periphery of an elongated object according to any one of the preceding claims, in which the drive device includes an element capable of sliding movement when the brake is activated.
