A tool for roughening a borehole surface. The tool includes a coupling portion for clamping the tool in a drilling machine; and a tool head for machining the borehole surface, where the tool head comprises a cutter that is circumferentially disposed on the tool head, and where the tool head has at least one slit, which passes through from one side to the other and which, starting from an end face of the tool head, and extends axially along a longitudinal axis of the tool.

Tool for roughening a borehole surface

An extrusion device for compound-containing containers, including a receiving chamber for the container, a piston rod which is displaceable relative to the receiving chamber and further including an extrusion mechanism having an advancing mechanism for advancing the piston rod. A wiper element is provided which has a wiper edge facing the piston rod.

Extrusion device

A dispenser () for dispensing the contents of cartridges (), including an advancing mechanism () for a piston rod (), a housing () on which a transmission lever () for actuating the advancing mechanism () is attached so as to swivel, and a handle (), which is affixed to the housing and to which an actuation lever () is attached so as to swivel, whereby the transmission lever () and the actuation lever () are connected to each other in an articulated manner via a sliding block guide ().

Dispenser for dispensing the contents of cartridges with actuation lever

An extrusion device for the extrusion of single- or multi-component materials from at least one container is provided. The extrusion device includes a housing having a functional section and a manual operation section. The housing extends substantially along an axial direction. The functional section includes at least one container receptacle. The manual operation section includes a lever arrangement via which an extrusion rod arrangement can be actuated to extrude materials from the at least one container. The lever arrangement includes a lever body mounted on a rotary axis. The lever body includes a lever push arm on one side of the rotary axis and a lever grip arm on the other side of the rotary axis. The lever push arm acts in a force-transmitting manner on a drive body attached on the extrusion rod arrangement upon actuation of the lever grip arm. The lever body includes a fork which forms at least two fork sections, and a fork trunk, wherein each of the at least two fork sections each extends into a lever push arm, and the fork trunk extends into the lever grip arm.

An ejection device for a mass-containing package () includes at least one piston rod () having a toothing () extending along its longitudinal extent, and a drive unit () for displacing the at least one piston rod () and having at least one gear wheel () engageable with the toothing () of the at least one piston rod () and displaceable from a first position, in which it engages the toothing () of the at least one piston rod (), to a position in which it is disengaged from the toothing () of the at least one piston rod, and a drive motor () for driving the at least one gear wheel ().

Ejection device

An ejection device () for cartridges containing multi-component compounds has an ejection mechanism () and a receptacle () for the cartridge, with the receptacle () being limited on the front side by a head plate () and on the rear side by a stop plate () and in order to hold the cartridge in a first position, a first stop () provided at the head plate () and a second stop () provided in the area of the stop plate (), and a third stop () in order to hold the cartridge in a further position.

A cartridge () used as a container for a compound that can be ejected by an ejection device, has two receptacles () and a head part (), each receptacle () having a receptacle chamber () for components of the compound with the head part () having a base plate () with an outlet opening () for the compound and, at a contact surface () of the base plate (), two guide portions () for joining to an end () of the corresponding receptacle (), a guide element for the receptacle () arranged adjacent to the guide portion () at the contact surface () of the head part ().

Cartridge for an ejectable compound

A dispensing device () for dispensing one-component or multi-component masses contained in vessels has a piston rod () and a forward feed mechanism (). The forward feed mechanism () has a first clamping lever () and a second clamping lever () each of which is arranged on the piston rod () so as to be axially displaceable and swivelable in longitudinal direction (L) of the dispensing device (). At least two spring elements () act upon the clamping levers (). The device () further includes forward feed means for actuating the first clamping lever () and the second clamping lever () and having a first forward-feed element () cooperating with the first clamping lever () and a second forward-feed element () cooperating with the second clamping lever ().
